L1: Power inductor Inductance:1.0mH, Rating current: above 0.74A Choose components that do not easily get magnetically saturated in high temperature. Recommended part : C13-FR 1.0mH (MITSUMI) D1: Flywheel diode Above 1000V, current: above 1.0A Fast recovery diode Please note that both the switching and efficiency characteristics of the module are affected by this diode. Recommended products: UF4007 (VISHAY) D2: Rectifier diode Use a rectifying diode with the peak reverse voltage of 1kV or higher, the average rectification current of 1A or larger and the peak surge current of 20A or larger. When using an input capacitor of a large capacity, choose a component that endures the inrush current on power-up. This product is compatible with full-wave rectification.
