Please verify operation and characteristics in the customer's circuit before actual usage. Ensure that the load current does not exceed the maximum rating. External Component Specifications FUSE: Fuse C1: Input smoothing capacitor C2: Noise reduction capacitor C3: Capacitor for Output voltage smoothing Please make sure to use a fuse of 0.5A Capacitance : 3.3 to 22µF Rated voltage : 250V or higher Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher Use a film or ceramic capacitor and evaluate characteristics under actual operating conditions. Capacitance : 100 to 470µF Rated voltage : 25V or higher Impedance is 0.39Ω max at high frequency range. Ripple current is 0.1Arms above. Capacitor impedance affects the output ripple voltage. In the absolute maximum ratings, the reverse surge voltage should be 400V or higher, the average rectifying current should be 0.5A or higher, and the forward surge current 20A or higher. 10 to 22Ω, 1/4W Use for terminal voltage noise reduction. Determine the optimal value through actual testing. A varistor must be used to protect the part against lightning surges and static electricity.
