How to Choose Capacitor Size More Accurately(III)

The working voltage of the capacitor should meet the requirements of the circuit. In general, the rated voltage of the selected capacitor should be 1.21.3 times of the actual working voltage. For the circuit with high temperature or poor stability in the working environment, the rated voltage of the capacitor should be taken into account in order to keep a larger margin. If the working voltage in the capacitor circuit is higher than the rated of the capacitor, it is easy make the capacitor break down, which makes the whole circuit unable to work normally. The rated voltage of capacitor generally refers to DC voltage. If it is used in AC circuit, it should be selected according to the characteristics and specifications of capacitor; if it is used in pulsating circuit, the sum of AC and DC components should not exceed the rated voltage of capacitor.
