C4: For noise terminal voltage Above 600V, 0.1 to 0.22µF
reduction capacitor
Film capacitor or Ceramic capacitor
Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
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.
R1: For noise terminal voltage 10 to 22â¦, 1W
reduction capacitor
Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
ZNR: Varistor
Varistor must be used. It protects this part from lightning surge and static electricity.
