Especially right attention has to be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple voltages increase. 100 Output Current Io(mA) Parameter Input voltage Operating temperature range Storage temperature range Case temperature Output current Dimensions (Unit : mm) 80 60 Operation Range 40 20 0 -30 -20 -10 0 10 20 30 40 50 60 70 80 90 100 Ambient Temperature Ta(°C) Application Circuit Be sure to use fuse for safety. R1 5 6 7 FUSE A − Vi ZNR + − C1 C3 C2 + − V − Vo Please verify operation and characteristics in the customer's circuit before actual usage. Ensure that the load current does not exceed the maximum rating. FUSE: Fuse Use a quick-acting fuse (1.0A) C1: Input capacitor above 250V, 10 to 47µF C2: Output capacitor above 25V, 47 to 470µF, Low impedance ESR:0.42Ω Max. Ripple current 0.2Arms or greater Capacitor impedance affects the output ripple voltage. C3: Noise reduction capacitor Above 250V, 0.1 to 0.22µF Film or ceramic capacitor. Evaluate under actual operating conditions. R1: Noise reduction resistor 10 to 100Ω, 1/4W Determine the ideal value through actual testing. D1: Rectifier diode Use a rectifying diode with a peak reverse voltage of 400V or higher, an average rectification current of 1A or larger and a peak surge current of 40A or larger. When using a large capacitance input capacitor, select a component that is strong against inrush current during power up. Full-wave rectification can be used. A varistor is required to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd.
