High-voltage capacitor in a low-voltage system

Quick question: is using a capacitor rated for high voltage (let''s say 35 V) in a system that, let''s say, supplies 5 V (like for LEDs or what have you) dangerous? Since it can store up to 35 V, will it like somehow store a bunch and then release it at once, damaging the system, or it is OK to use a higher-rated capacitor than the voltage being supplied? capacitor; voltage; Share.

What does the Voltage Rating on a Capacitor Mean?

Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely.

What does the Voltage Rating on a Capacitor Mean?

The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. 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

Capacitor Characteristics

Nevertheless, the DC working voltage of a capacitor is the maximum steady state voltage the dielectric of the capacitor can withstand at the rated temperature. If the voltage applied across the capacitor exceeds the rated working voltage, the dielectric may become damaged, and the capacitor short circuited.

Is it a problem to use a capacitor at or near its rated DC voltage?

For electrolytic caps, they are (generally) able to withstand twice the rated voltage for 1 or 2 seconds. So, having the voltage close to its rated shouldn''t be a problem. However... Like in other components, a capacitor''s ratings need to be de-rated with external conditions (e.g. temperature). This means that a capacitor''s voltage rating might be lower for

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).
