Ripple current 1Arms or greater Capacitor impedance affects effects the output ripple voltage R1: Noise reduction resistor ZNR: Varistor Inductance : 330µH, Rating current : above 1.6A Select components that do not easily get magnetically saturated at high temperature. Above 400V, current : above 3A Fast recovery diode Please note that both the switching and efficiency characteristics of the module are affected by this diode. Recommended products : 31DF4 (Nihon Inter) or RU30 (Sanken) 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 20A 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. 1 to 2.2Ω, 1/4W Reduce the noise terminal voltage. Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity. www.rohm.com ©2010 ROHM Co., Ltd.
