Ensure that the load current does not exceed the maximum rating. External Component Specifications A varistor is required to protect against lightning surges and static electricity. 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 peak surge current should be 20A or higher. (Full-wave rectification can be used.) C3: Input smoothing capacitor Rated voltage : 200V or higher. Capacitance : 33 to 330µF FL1: Noise reduction filter Use a line filter if necessary. C1,2,4 : Noise reduction capacitors Capacitance (C1,C2) : 0.1 to 0.22µF, (C4) : 4700pF Rated voltage : 200V or higher. Film or ceramic capacitor. Evaluate under actual operating conditions.
