5 Capacitor Facts You Should Know

The voltage rating displays the "not to exceed" rating, which means you can replace a 370v with a 440v, but you cannot replace a 440v with a 370v. This misconception is so common that many capacitor manufacturers began stamping 440v capacitors with 370/440 to eliminate confusion.

How to pick voltage rating for capacitors

Depending on the dielectric, ceramic capacitors derate based on the DC voltage applied. The higher the voltage rating compared to the applied DC voltage, the less they derate. So you will have more effective capacitance with the 20V rated part than the 6.3V rated part. This does not apply to (polymer) tantalums, film caps, or electrolytics.
