Please verify operation and characteristics in the customer's circuit before actual usage and ensure that the load current does not exceed 0.6A. External Component Specifications FUSE: Fuse Use a quick-acting fuse (2A) C1: Input capacitor Above 200V, 47 to 220µF Ripple current 0.22Arms or greater C2: Noise reduction Above 200V, 0.1 to 0.22µF capacitor Use a film or ceramic capacitor. Evaluate under actual operating conditions. C3: Output capacitor Above 50V, 330 to 1000µF, low impedance ESR : 0.08Ω Max. Ripple current 1Arms or greater Capacitor impedance affects the output ripple voltage. L1: Power inductor Inductance : 1.0mH, Rating current : above 1.2A 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. 1.0 to 2.2Ω, 1/4W Determine the ideal value through actual testing. A varistor is required to protect against lightning surges and static electricity.
