What is a capacitor size?

It’s a tool for determining the physical size of capacitors based on their capacitance and voltage rating. Why is capacitor size important? It affects the fit and functionality of capacitors in electronic circuits. How do I calculate the size of an aluminum electrolytic capacitor?

What size capacitor do I need for a 12V circuit?

Example 2: For an input voltage (X) of 12V and required capacitance (Y) of 10uF, the tool will recommend the appropriate capacitor size for a 12V circuit needing 10uF of capacitance. Our Capacitor Size Calculator ensures your data's security as it operates entirely client-side.

How do you choose a capacitor size?

When considering the capacitor size for a given application, parameters such as voltage, current ripple, temperature, and leakage current must be considered. Capacitor size selection is important, considering the physical size and capacitance aspects, as they affect circuit assembly and the performance variation of the circuit.

Which capacitor size is suitable for a 5V circuit?

Example 1: If the input voltage (X) is 5V and the desired capacitance (Y) is 1uF, the output will be the capacitor size suitable for a 5V circuit with 1uF capacitance. Example 2: For an input voltage (X) of 12V and required capacitance (Y) of 10uF, the tool will recommend the appropriate capacitor size for a 12V circuit needing 10uF of capacitance.

What is the maximum voltage a capacitor can handle?

The maximum voltage a capacitor can handle is determined by its voltage rating. It is important to know what you are dealing with. Never exceed the voltage rating of a capacitor, such as 25V for a 25V rated capacitor or 16V for a 16V rated capacitor. Using a higher voltage rating capacitor, like a 50V capacitor instead of a 16V or 25V one, has no effect.

Can I use a 50V capacitor instead?

Yes, you can use a 50V capacitor. The only difference will be a bigger can size and a very slightly improved reliability which you probably won't notice. What happens if you use the wrong size capacitor?
