∗1 Max output current should be reduced according to the surrounding temperature. ∗2 The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. 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.

External Component Specifications FUSE: Fuse C1: Input capacitor C2: Output capacitor Use a quick-acting fuse (1.0A) above 250V, 10 to 47µF above 25V, 47 to 470µF, Low impedance ESR:0.42Ω Max. Ripple current 0.2Arms or greater Capacitor impedance affects the output ripple voltage. Above 250V, 0.1 to 0.22µF Film or ceramic capacitor. Evaluate under actual operating conditions. 10 to 100Ω, 1/4W Determine the ideal value through actual testing. 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.
