C3: Noise removal capacitor
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 : C13FR (MITSUMI)
R1: For noise terminal voltage reduction resistor D1: Flywheel diode Above 600V, current : above 2.0A, Fast recovery diod e Please note that both the switching and efficiency characteristics of the module are affected by this diode. Recommended part : CMF01 (Toshiba) Use a rectifying diode with the peak reverse voltage of 800V or higher, the average rectification current of 1A or large and the peak surge current of 20A or large.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. Be sure to use it to protect this product from thunder surge and the static electricity.
D2: Rectifier diode
ZNR: Varistor
