Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. Capacitance : 100 to 470µF Rated voltage : 50V or higher, ESR is 0.39 max. Ripple current is 0.1Arms or greater. Evaluate under actual operating conditions. In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current should be 0.5A or higher, and the forward peak current should be 20A or higher. (Full-wave rectification can be used.) 10 to 22Ω 1/4W Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity.
