For capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitance withstand voltage derating should be 80% or above. C1 is ceramic capacitor, which is used to filter high-frequency noise. If operation voltage of the module is lower than 165VAC, then need external capacitor C3, C3 can use film capacitors or electrolytic capacitor. If C3 use electrolytic capacitors, when the film capacitors is under 120HZ, require the LN03-12Bxx series corresponding ripple current rating must be greater than 80mA, the LN02-12Bxx series must be greater than 40mA, the LN01-12Bxx series must be greater than 30mA, and the capacitors’ shelf life should more than 5 years. 2.
