Capacitor impedance affects the output ripple voltage. C3: Noise reduction capacitor Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher Use a film or ceramic capacitor. Evaluate under actual operating conditions. D1: Rectifier diode In the absolute maximum ratings, the reverse peak voltage should be 400V or higher, the average rectifying current should be 1A or higher, and the forward surge current should be 40A or higher. R1: Noise reduction resistor 10 to 22Ω 1/4W Determine the ideal value through actual testing. ZNR: Varistor A varistor is required to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd.
