Before we explore the combining process, let’s briefly understand what nonpolar capacitors are. Unlike their polar counterparts, such as electrolytic capacitors, nonpolar capacitors lack distinct positive and negative terminals. This characteristic makes them adaptable to diverse applications.

Collecting Your NonPolar Capacitors

Before you dive into combining nonpolar capacitors, start by gathering the capacitors you plan to use. Be sure that all these capacitors share the same capacitance value to avoid circuit imbalances.

Parallel Connection

One common method to combine nonpolar capacitors is through parallel connection. This approach increases the total capacitance while keeping the voltage rating consistent.

Identify the Terminals

Now, let’s get up close and personal with your nonpolar capacitors. Each one typically has a pair of terminals, often marked as “+” and “-“. Here’s the drill: connect all those “+” terminals, and do the same with the “-” terminals. It’s like introducing old friends who are meant to work together seamlessly.

Use appropriate wires or connectors to establish these connections. Ensure that there is a solid electrical connection between the terminals to guarantee proper functionality.

Total Capacitance

The total capacitance of your combined capacitors in parallel is the sum of the individual capacitance values. This configuration proves beneficial when you need to boost capacitance while maintaining the voltage rating.

Series Connection

Another method to combine nonpolar capacitors is through a series connection. This method raises the total voltage rating while preserving the same capacitance value.

Identify the Terminals

As before, identify the “+” and “-” terminals of each capacitor. In this case, you’ll connect the “+” terminal of one capacitor to the “-” terminal of the next.


Utilize appropriate wiring to connect the capacitors in series. Ensure secure connections to maintain proper functionality.

Total Voltage Rating

Now, when you’ve got capacitors playing together in series, something interesting happens. The total voltage rating in this setup becomes the sum of the individual capacitors’ voltage ratings. This nifty configuration comes in handy when you’re aiming to boost your circuit’s voltage tolerance.

Double-Checking Polarity

Before you hit the power button on your circuit, there’s one last important task – the polarity check. It’s crucial to take a moment to ensure that your connections are in the right order. Trust us; a mix-up in polarity can spell trouble, potentially causing harm to the capacitors and other precious components in your circuit. So, it’s a small step that’s big on preventing mishaps.

Combining nonpolar capacitors is an essential skill in electronic circuit design. Whether you’re looking to increase capacitance or voltage tolerance, knowing how to connect them in parallel or series is vital to meet your project’s requirements. Carefully follow these steps, and your combined nonpolar capacitors should perform effectively in your circuit.


Q1: How do you combine two capacitors?

A1: Combining two capacitors can be done in two primary ways: in parallel or in series. In parallel, you connect the positive terminals together and the negative terminals together. In series, you connect the positive terminal of one capacitor to the negative terminal of the other.

Q2: How do you combine capacitors in parallel?

A2: Combining capacitors in parallel involves connecting the positive terminals of the capacitors together and the negative terminals together. This setup increases the total capacitance while maintaining the voltage rating.

Q3: What are non-polarized capacitors used for?

A3: Non-polarized capacitors, such as ceramic or film capacitors, find their place in various electronic applications where you don’t have to worry about the voltage’s polarity across the capacitor. You’ll often spot them in circuits used for tasks like signal coupling, filtering, and timing.

Q4: What sets apart a non-polar capacitor from a polar one?

A3: Non-polarized capacitors, like ceramic or film capacitors, are used in various electronic applications where the polarity of the voltage across the capacitor isn’t critical. They are commonly used in signal coupling, filtering, and timing circuits.

Q4: What is the difference between a nonpolar capacitor and a polar capacitor?

A4: The key distinction boils down to polarity. Polar capacitors, like electrolytic capacitors, come with specific positive and negative terminals. In contrast, nonpolar capacitors don’t have such concerns. You can plug them into your circuit in either direction without any fears of polarity-induced damage.
