6 FAQs about [Capacitor rated voltage level]

What is a capacitor voltage rating?

The voltage rating is the maximum voltage that a capacitor is meant to be exposed to and can store. Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it.

Should a capacitor be rated 50 volts?

So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor).

Why do capacitors have different voltage ratings?

A capacitor with a 12V rating or higher would be used in this case. In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.

How to choose a capacitor based on voltage rating?

When choosing a capacitor, the voltage rating is an important consideration. It indicates the maximum voltage that can be applied across the capacitor. The dielectric of a capacitor breaks down when voltage is applied beyond its rating, which is known as electrical breakdown.

How do I choose a capacitor voltage rating?

Adequate safety margins should be used when choosing capacitor voltage ratings for an application, with higher safety factors for critical reliability. General guidelines include: Minimum 2x margin between working voltage and rated voltage for general purpose capacitors. Minimum 10-20% margin for capacitors in power supplies and power conversion.

What happens if a capacitor exceeds rated voltage?

Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
