    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.

    This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It depends to your budget because the higher the voltage, the expensive the capacitor is.

    Which capacitor should be used in a pulsating circuit?

    The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.

    What determines the maximum voltage of a capacitor?

    When designing a capacitor, the maximum voltage is determined by the insulator between the metal plates. Roughly speaking, the thicker the insulator, the higher the voltage it can stand, though some insulators are better than others. But the thicker the insulator, the lower the capacitance.
