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.

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.

How do you read capacitor markings?

Reading capacitor markings involves identifying several key attributes. The capacitance value often marked directly in microfarads (μF), nanofarads (nF), or picofarads (pF). The voltage rating indicates the maximum voltage the capacitor can handle, marked as a number followed by "V".

How to choose a capacitor?

Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, etc.). So when choosing a capacitor you just need to know what size charge you want and at which voltage.

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).

How do I know if a capacitor has a voltage rating?

There are different types of representations for the voltage rating of these capacitors. Sometimes it is written clearly on the enclosure of the capacitor with its unit. For some disk capacitors, it is represented by a single underline after the capacitance value. This underline shows 100 V as the maximum working voltage.
