C2: Noise removal capacitor C3: Output capacitor Load Regulation Above 200V, 0.1 to 0.22µF Film or ceramic capacitor Reduce the noise terminal voltage. The value should be verified under actual conditions. Above 25V, 100 to 470µF, low impedance ESR : 0.39Ω Max. Ripple current 0.1Arms or above Capacitor impedance affects the output ripple voltage. R1: Noise removal resistor Resistance : 10 to 22Ω, Power : More than 1/4Ω D1: Rectifier diode Use a rectifying diode with a peak reverse voltage of 400V or higher, an average rectification current of 0.5A or larger and a large capacity input capacitor, peak surge current of 20A or larger. When using a large capacity input capacitor, choose a component that is strong against inrush current during startup. This product is compatible with full-wave rectification. ZNR: Varistor A varistor must be used to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd. All rights reserved.
