Using capacitor with lower voltage than the specified one

It recommends to use a 33pF 63V capacitor. I''m in trouble to find a capacitor with this specific voltage. I only found a 33pF 50V one. ... Your circuit is running at plus minus 20V. A capacitor voltage rating of 25V is marginal, so I would choose a capacitor voltage rating at 35V or more. Your 50V capacitor will be just fine. Share.

What happens if I connect a low voltage rated capacitor to a high voltage?

For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don''t have a capacitor any more. In the best case you are left with a short circuit or ...

OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

All-pMOS 50-V Charge Pumps Using Low-Voltage Capacitors

Nonetheless, these high-density capacitors suffer from low breakdown voltage, which is not compatible with the targeted high-voltage application.

The two CP circuits were fabricated in a 0.6- μm CMOS technology ...

What is the lowest capacitor voltage rating that is safe to use?

The lighter the stress on a capacitor the less margin I will allow. For example, if a signal only very occasionally goes to 90V but is mostly below 50V then I might use a 100V ceramic capacitor. Temperature, voltage, current, and ESL/ESR effects all play into this. A capacitor with lots of stress will get much more of a margin. Derating less ...
