Film capacitor or Ceramic capacitor

Reduce the noise terminal voltage.

The constant value should be evaluated in the product.

C2: Noise removal capacitor

Resistance : 10 to 22

Ω, Power : More than 1/4Ω

R1: Noise removal resistor

Use a rectifying diode with the peak reverse voltage of 400V or higher,

the average rectification current of 0.5A 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.

D1: Rectifier diode

Varistor must be used. It protects this part from lightning surge and static

electricity.

ZNR: Varistor
