How to choose a capacitor for a motor?

When replacing these capacitors, the capacitance value and voltage should be taken from the manufacturer’s plate on the motor or from the old capacitor.This must be correct within ±5% and is sometimes stipulated down to a fraction of a μF.The choice of a running capacitor is even more limited than with a starting capacitor.

How is a capacitor rated?

Usually, capacitors are derated by the following rule of thumb: a capacitor is selected such that its voltage rating is two to three times greater than the expected operating voltage. Derating increases the footprint requirements of the capacitor because, with an increase in working voltage, the physical size of the capacitor also increases.
