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 capacitor C2: Noise removal capacitor Use a quick-acting fuse (0.5A) Above 200V, 3.3 to 22µF Ripple current 0.13Arms or above. 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. Resistance : 10 to 22Ω, Power : More than 1/4Ω 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. A varistor must be used to protect against lightning surges and static electricity. 0 5 10 15 20 25 Output Current Io(mA) 30 Load Regulation 5.3 Output Voltage Vo(V) 5.2 5.1 5.0 4.9 4.8 4.7 0 5 10 15 20 25 Output Current Io(mA) 30 Load Regulation (Ta=25°C, Vi=141V) C3: Output capacitor R1: Noise removal resistor D1: Rectifier diode Surface Temperature Increase Temperature Rising ∆T(°C) 50 40 30 20 10 0 0 Surface Temperature Increase (Ta=25°C, Vi=141V) ZNR: Varistor 5 10 15 20 25 Output Current Io(mA) 30 www.rohm.com ©2010 ROHM Co., Ltd.
