reduce the noise terminal voltage.
The constant value should be evaluated in the product.
Inductance : 1mH, Rating current: above 400mA
Choose components that do not easily get magnetically saturated in
high temperature.
Recommended part : C10-FR 1.0mH(MITSUMI)
Use a rectifying diode with the peak reverse voltage of 800V 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 products is compatible with full-wave rectification.

Reduce the noise terminal voltage.
The constant value should be evaluated in the product.
Varistor must be used. It protects this part from lightning surge and static
electricity.
