Last Updated on 2 weeks by A. Hamza

How to combine non nonpolar capacitors? Ah, nonpolar capacitors! Just hearing the term sends a few of us spiraling back to that high school physics class, where capacitors seemed like a concept as distant as Pluto (still not over its downgrade from planetary status, by the way). But here you are, ready to delve into the enigmatic world of combining these components.

Combining nonpolar capacitors isn’t just about shoving two pieces together and hoping for a zap of success. No, it’s an art, a dance of sorts. Think of it as a choreography where each step, each twirl, needs precision, or you might end up stepping on your partner’s toes (or, in this case, frying your circuit).

If you’ve ever wondered how to merge these components without causing an electrical apocalypse, you’re in the right place. Strap in because we’re about to demystify the process, give you actionable steps, and, yes, sprinkle in a few laughs along the way. After all, who said electronics can’t be electrifyingly fun?

Why Combine Non-Nonpolar Capacitors?

Non-nonpolar capacitors are also known as non-polarized capacitors. They are a type of capacitor that can be used in either direction without regard to polarity. This makes them very versatile and useful in a wide range of applications.

There are a few reasons why you should combine non-nonpolar capacitors. One reason is to increase the overall capacitance of the circuit. For example, if you need a 100 µF capacitor but you only have two 50 µF capacitors, you can connect them in parallel to create a 100 µF capacitor.

Another reason to combine non-nonpolar capacitors is to reduce the overall size of the capacitor. For example, if you need a 100 µF capacitor but are limited on space, you can connect two 50 µF capacitors in series to create a 100 µF capacitor.

Finally, combine non-nonpolar capacitors to improve the overall performance of the circuit. For example, if you are using a non-nonpolar capacitor in a high-frequency circuit, you can connect two capacitors in parallel to reduce the overall impedance of the capacitor.

Here are some specific examples of when you might want to combine non-nonpolar capacitors:

  • To increase the overall capacitance of the circuit. For example, if you need a 100 µF capacitor but you only have two 50 µF capacitors, you can connect them in parallel to create a 100 µF capacitor.
  • To reduce the overall size of the capacitor. For example, if you need a 100 µF capacitor but are limited on space, you can connect two 50 µF capacitors in series to create a 100 µF capacitor.
  • To improve the overall performance of the circuit. For example, if you are using a non-nonpolar capacitor in a high-frequency circuit, you can connect two capacitors in parallel to reduce the overall impedance of the capacitor.
  • To create a non-polar electrolytic capacitor. This is done by connecting two electrolytic capacitors in series, back-to-back. This allows the electrolytic capacitors to be used in applications where the polarity is not known or can change.

When combining non-nonpolar capacitors, it is important to make sure that the capacitors have the same voltage rating. You should also make sure that the capacitors are connected in the correct direction. 

For example, if you are connecting two capacitors in parallel, the positive terminals of the capacitors should be connected, and the negative terminals of the capacitors should be connected.

If you need help with how to combine non-nonpolar capacitors, it is always a good idea to consult with a qualified electrician.

Understanding Nonpolar Capacitors: A Quick Refresher

Alright, folks! Let’s iron out some basics before we embark on this electrifying adventure. Remember those long, tedious physics classes where you daydreamed about pizza more than paying attention to capacitors? Time for a memory jog sans the classroom setting.

What Exactly are Nonpolar Capacitors?

In the grand tapestry of electronics, capacitors are like the unsung heroes, often overshadowed by their flashy neighbors like transistors and diodes. A capacitor stores energy at its heart, but the real drama unfolds when we talk about the nonpolar variety.

Unlike their polar counterparts with a definite positive and negative side, nonpolar capacitors are the easy-going ones in the family. No definitive positive or negative; they’re like the Switzerland of capacitors – neutral and versatile.

Why Nonpolar?

You might wonder, “Why go nonpolar?” It’s like asking, “Why would someone prefer pineapple on pizza?” (The debate continues!). Nonpolar capacitors are useful in alternating current (AC) circuits because of their neutrality. They don’t discriminate between reverse and forward voltage, making them the peacekeepers in the turbulent world of AC.

Their Day-to-Day:

To add real-world context, these little guys are often found in audio systems, ensuring your favorite tunes sound right. Imagine a guitar riff that doesn’t sound crisp or a bass drop that’s less than dramatic. Yep, you can often thank a misbehaving nonpolar capacitor for that!

To wrap up our refresher, nonpolar capacitors are the adaptable, neutral members of the capacitor clan, ensuring balance in AC circuits and harmony in our electronic devices. And just like any well-balanced diet requires a mix of veggies and the occasional chocolate chip cookie, a good electronic design often relies on a mix of polar and nonpolar capacitors.

So, now that we’re all on the same page (or circuit board) let’s delve deeper into how to combine these little wonders!

Types of Non-Nonpolar Capacitor Combinations

Non-nonpolar capacitors, also known as non-polarized capacitors, are a type of capacitor that can be connected in either direction without regard to polarity. This makes them very universal and usable in a wide range of applications.

There are two main types of non-nonpolar capacitor combinations: series and parallel.

Series Capacitor Combinations

When capacitors are linked in string, the general capacitance of the combination is less than the capacitance of any individual capacitor. This is because the capacitors are essentially acting as one large capacitor, with the plates of the capacitors connected in series.

The formula for calculating the capacitance of a series capacitor combination is:

1 / C_total = 1 / C_1 + 1 / C_2 + … + 1 / C_n


  • C_total is the capacitance of the series combination
  • C_1, C_2, …, C_n are the capacitances of the individual capacitors

Series capacitor combinations are often used to reduce the overall size of a capacitor or to increase the voltage rating of a capacitor.

For example, if you need a 100 µF capacitor with a voltage rating of 200 V, you could connect two 50 µF capacitors with a voltage rating of 100 V in series. This would give you a 100 µF capacitor with a voltage rating of 200 V.

Parallel Capacitor Combinations

When capacitors are connected in parallel, the overall capacitance of the combination is equal to the sum of the capacitances of the individual capacitors. This is because the capacitors are essentially acting as multiple small capacitors, with the plates of the capacitors connected in parallel.

The formula for calculating the capacitance of a parallel capacitor combination is:

C_total = C_1 + C_2 + … + C_n


  • C_total is the capacitance of the parallel combination
  • C_1, C_2, …, C_n are the capacitances of the individual capacitors

Parallel capacitor combinations are often used to increase the overall capacitance of a circuit or to reduce the overall impedance of a capacitor.

For example, if you need a 200 µF capacitor, you could connect two 100 µF capacitors in parallel. This would give you a 200 µF capacitor.

What exactly are capacitors that have nonpolar characteristics used to do?

Nonpolarized capacitors can be found in a wide variety of electronic and electrical circuits. They are typically used in the following areas:

  1. Coupling The capacitors that have no polarization are employed to join or link various stages of an amplifier as well as other electronic circuits.
  2. Decoupling These devices are utilized to reduce unwanted noise as well as stabilize the voltage of the power supply within electronic circuits.
  3. Feedback The nonpolarized capacitor plays a part in feedback circuits. They can be used to regulate the frequency response and gain of amplifiers.
  4. Compensation The Compensation is utilized to reduce the resonance of amplifiers and different electronic circuits.
  5. Circuits for oscillators: Nonpolarized capacitors may be utilized in oscillator circuits to create continuous oscillations.

They are also utilized to provide bi-directional signals for audio-related applications.

It is important to note that capacitors without polarization are not polarized and do not possess an inverse polarity that is positive or negative, which allows them to be used in any direction in the circuit. They tend to be bigger than polarized capacitors that have identical capacitance.

What are some kinds of capacitors that are nonpolar?

Nonpolarized capacitors are utilized for a range of electronic and electrical circuits. Different types of capacitors that are nonpolarized are:

  1. Ceramic capacitors The HTML0 capacitors are the most widely utilized capacitors that are not polarized. They come in disk or block-shaped versions and deliver the best performance in terms of stability, low-loss and efficiency.
  2. Silver mica capacitors are stable and temperature-tolerant. They can be used for filter circuits and oscillators.
  3. Capacitors made of polystyrene The capacitors have constant capacitance with respect to voltage, frequency, and temperature.
  4. Capacitors made of polypropylene have outstanding electrical properties and are widely employed in audio-related applications.
  5. Polyester capacitors The capacitors listed above are used extensively due to their cost-effectiveness and excellent electrical properties.
  6. Teflon capacitors have outstanding temperature stability and perform well.
  7. Capacitors made of polycarbonate The capacitors are known for their excellent electrical properties and can be employed in many electronic circuits.
  8. Glass capacitors They can operate at high voltages and are utilized in amplifiers, resonance circuits, high voltage inverters, radio broadcast transmitters, and more.

Here are a few examples of the types of nonpolarized capacitors. Each one has its distinct characteristics and uses.

It is important to note that unpolarized capacitors are not polarized and do not possess the polarity of negative or positive, which allows them to be connected to any direction inside the circuit.

What’s the difference between nonpolar and polar capacitors?

The major difference between polar and nonpolar capacitors is that polarized ones include negative and positive terminals. Nonpolar capacitors don’t have opposite polarity. They can be employed in a single direction in an electrical circuit. Nonpolar capacitors are able to be utilized both ways. The majority of the time, polarized capacitors are utilized in DC circuits. However, nonpolar capacitors are utilized for AC circuits.

Nonpolarized capacitors are available in various types such as ceramic, silver mica, polystyrene, polypropylene, polyester, Teflon, polycarbonate, glass, power, motor, DC-link, suppression, audio crossover, lighting ballast, snubber, and coupling/decoupling/bypassing capacitors. They are typically employed in circuits for coupling, decoupling, as well as compensation and oscillation.

The Logic Behind Combining: Why Two is Better Than One

In the vast universe of electronics, capacitors are much like those iconic duos in our favorite buddy cop movies – individually fantastic but truly legendary when paired up. Let’s dive into why that’s the case!

Why Combine in the First Place?

Before you even think of getting two nonpolar capacitors on a playdate, it’s essential to understand why you’re doing it. Combining capacitors can help achieve a desired capacitance that might not be readily available. Imagine wanting a specific shade of blue paint. You don’t have it, but you have light blue and dark blue. Mix them, and voilà! Perfect shade. Similarly, by combining capacitors, you’re custom-creating a capacitance value. It’s DIY for techies!

Enhanced Performance:

You’re getting the best of both worlds when you successfully pair up nonpolar capacitors. In the same way, you’d enjoy a double scoop of ice cream (because why settle for one flavor when you can have two?), having two capacitors together can offer you increased performance in terms of voltage, energy storage, or lifespan. The dynamic duo, indeed!

Cost and Availability:

Sometimes, it’s just a matter of practicality. The exact capacitance you need might be pricier or out of stock. It’s akin to wanting that gourmet burger from a fancy joint, but realizing a DIY sandwich at home (with all the toppings) is quicker, cheaper, and just as tasty! Combining readily available capacitors can save both time and pennies.

The Spice of Variety:

Variety is the spice of life, and the same goes for capacitors. Different combinations can provide unique characteristics suitable for specific applications. It’s like switching dance partners: sometimes, you need the quick-paced jive, and other times, the slow, calculated waltz. Knowing how to pair capacitors gives you flexibility in your design moves.

Wrapping It Up:

Remember, combining nonpolar capacitors is like creating a perfect sandwich. Sure, ham and cheese are great alone, but together? Culinary harmony. Likewise, with the right knowledge and a dash of humor, you’ll combine capacitors like a pro in no time!

Tip #1: The Right Tools for the Task

As the saying goes, “You wouldn’t use a sledgehammer to crack a nut.” Similarly, you would want to avoid using household tools when dealing with delicate electrical components like nonpolar capacitors. Let’s ensure your DIY capacitor venture doesn’t turn into a comedy sketch!

Precision Tweezers and Pliers:

First on our superstar list are precision tweezers and pliers. Their elegant and sleek design ensures you can grasp tiny capacitor legs without turning it into a game of ‘Operation’ (and, trust me, the buzzing nose is the last thing you want here).

Soldering Iron:

For those joining the capacitor party, the soldering iron is your invite. Just remember, it’s hot stuff – literally. Ensure you’re not distracted by the latest episode of your favorite show. There’s a time and place for binge-watching, and this isn’t it!


Imagine going on a date without knowing the person’s name. Sounds silly. Well, a multimeter helps you ‘know’ your capacitor. It lets you check their voltage, resistance, and whether they’re still willing to cooperate.

Desoldering Tools:

Sometimes, capacitors can be clingy (don’t we all have that one friend?). For such moments, a desoldering tool or pump can help you break free without causing a scene.

Safety Glasses and Gloves:

While fashion may not be a priority when tinkering with capacitors, safety sure should be! Protect those peepers and pampered palms. After all, even superheroes have their protective gear, and they aren’t dealing with rogue capacitors!

Final Thought:

Using the right tools ensures the job gets done correctly, but your capacitor-combining saga doesn’t end up as something other than a slapstick story you sheepishly share at parties. So, tool up, champ! And remember, in the world of capacitors, it’s less about the size of the tool and more about how you use it.

Tip #2: Series or Parallel? Deciding the Dynamic Duo’s Dance

So, you’ve got your nonpolar capacitors ready, and you’re itching to combine them. Now comes the crucial question: series or parallel? Think of it as choosing between tango and salsa. Both dances have their allure, but your chosen style depends on the vibe you’re aiming for.

The Series Tango:

When capacitors are connected in series, they’re like dance partners in a tango – intensely connected yet relying on each other’s strengths. In the electric world:

  • The total capacitance decreases.
  • The voltage capability increases.

Benefits? You’ll get higher voltage handling. But here’s the humorous twist: It’s like wearing high heels for that added height advantage, but remember, it’s only sometimes comfortable.

The Parallel Salsa:

Salsa is all about vibrant individual moves, like capacitors in a parallel connection. Here:

  • The total capacitance adds up. More, the merrier!
  • Voltage remains the same.

It’s like dancing in sneakers – comfortable with added freedom but without the height.

Making a choice:

So, which dance should your capacitors groove to? Consider your circuit’s requirements. If you’re after a higher voltage, let them tango in series. But if it’s increased capacitance you’re aiming for, let them salsa in parallel.

Tip #3: Mind the Voltage – Not All Heroes Wear Capes

Alright, folks, strap in because this might be our adventure’s electrifying (pun intended!) heart today. Remember those superheroes that don’t wear capes? That’s right, nonpolar capacitors. But even superheroes have their kryptonite. For our little capacitor friends, it’s misjudged voltage.

Why Voltage Matters

Think of voltage in capacitors as the weight limit on an elevator. Just as overloading an elevator is a recipe for getting stuck between floors (and believe me, no one wants that awkward “waiting-for-rescue” chit-chat), overloading a capacitor beyond its voltage rating is, well… a potential firework display without the ‘oohs’ and ‘aahs.’

Finding the Right Fit

Each capacitor has its voltage rating. When combining nonpolar capacitors, especially in series, the voltage rating of the resulting combination can be different from individual ratings. It’s more than just basic addition, folks. It’s more like matchmaking – trying to find the perfect partner without causing any drama.

The Safety Margin

As with any great superhero movie, there’s always some wiggle room. It’s good practice to avoid pushing the capacitors to their max. Aim for using only up to 80% of a capacitor’s voltage rating. This safety buffer is your sidekick, ensuring things don’t go boom when you least expect.

A Voltage Chuckler

Ever heard of the capacitor who went on a voltage diet? He wanted to ‘discharge’ some excess weight. Okay, I promise, no more capacitor humor for at least the next two paragraphs!

Tip #4: Testing Before Trusting

Every good scientist, engineer, or anyone who’s ever bought a pair of jeans knows this golden rule: always test before fully committing. This isn’t just sage advice regarding nonpolar capacitors—it’s crucial.

Why Testing is a Must

Before we dive into the “how,” let’s discuss the “why.” Think of combining capacitors like setting up a blind date. Sure, on paper, the two seem compatible, but you’ll only know once they meet in person. In the world of electronics, this ‘meeting’ is your test. Without it, you risk system failures, a short lifespan of components, or, at worst, your circuit going up in metaphorical (or literal!) flames.

Gather Your Tools

For your capacitor testing session, you’ll need a multimeter. If you’re unfamiliar with this gadget, it’s the electronic world’s Swiss army knife. If you don’t have one, it’s worth the investment; after all, you wouldn’t try to catch a fish with your bare hands, would you?

The Testing Tango

  1. Visual Inspection: Start with a cursory glance. Check for any obvious deformities, bulges, or signs of damage. It’s a basic step, but sometimes we miss the forest for the trees.
  2. Measure the Capacitance: Using your multimeter, ensure the capacitor’s capacitance aligns with its rating. It’s okay if it’s a tad off (nobody’s perfect), but vast discrepancies are red flags.
  3. Check for Leaks: No, not the water kind. We’re talking about electrical leaks. A capacitor that leaks excessively can cause instability in your circuit.

Circuit Integration

Once you’ve ensured that your capacitors are in top-notch condition, integrate them into your circuit. But hold onto your horses! Before powering up the system, recheck all connections. Because as the old saying goes, “Better to be safe than sorry.” Or, in our case, “Better safe than sparking.”


Ah, the grand finale! We’ve embarked on a charged journey, from understanding the ins and outs of nonpolar capacitors to the careful art of combining them. If you’ve stuck with us through the capacitor tango and our milk analogy (still trying to figure out how that came in?), give yourself a pat on the back.

Recall our superhero duo comparison. Now, you’re equipped with the know-how to bring together Batman and Robin, or rather, our nonpolar capacitors, into a dynamic electrical alliance.

In a world full of complex jargon and even more complicated electronics, remember that every hero, or in this case, every electronics enthusiast, needs a set of trusty guidelines. These four super tips were yours.

And as you march forward, wielding soldering irons and capacitors, remember this electrifying piece of wisdom: every great combination starts with a spark (of knowledge, not literally, we hope!). So, plug into your newfound expertise, and here’s to many successful capacitor combinations!

Keep those capacitors and your humor closer until our next electronic escapade. Because, hey, if we can’t laugh at a capacitor joke, are we even charged up for life? Safe combining!
