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).

To determine the correct voltage rating for a capacitor, the working voltage of the circuit must be considered. A common rule of thumb is to select a capacitor with a voltage rating that is at least 1.5 times higher than the circuit’s maximum voltage.

Can a capacitor charge up to 50 volts?

A capacitor may have a 50-volt rating but it will not charge up to 50 volts unless it is fed 50 volts from a DC power source. The voltage rating is only the maximum voltage that a capacitor should be exposed to, not the voltage that the capacitor will charge up to.
