Please verify operation and characteristics in the customer's circuit before actual usage and ensure that the load current does not exceed 0.1A. FUSE: Fuse Use a fuse of 0.5A C1 : Input smoothing capacitor Capacitance : 3.3 to 22µF Ripple current is 0.13Arms or above. Rated voltage : 200V or higher C2 : Noise reduction capacitor Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. C3 : Output smoothing capacitor Capacitance : 100 to 470µF Rated voltage : 25V or higher, low impedance Impedance is 0.39Ω max at high frequencies. Ripple current is 0.1Arms or above. Capacitance 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 should be 20A or higher. R1 : Noise reduction resistor ZNR : Varistor 10 to 22Ω 1/4W Determine the ideal value through actual testing. A varistor must be used to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd.
