    FAQs about How to choose capacitor capacity for high voltage

    How to choose a capacitor?

    A capacitor with an appropriate ripple current and working voltage rating should be chosen. Polarity and Reverse Voltage – If an electrolyte capacitor is used in the circuit, it must be connected in the correct direction. Its reverse voltage rating should be at least twice the possible reverse voltage in that branch of the circuit.

    What should a capacitor's voltage rating be?

    Apart from nominal capacitance, the voltage rating is the second most important parameter that must be essentially factored in. The capacitor's voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors.
