Application enviromental

Ambient temperature range

Imunity Class

Emissions Class

Indoor industrial

-25°C ~ 55°C

Class IV

Class B

Component

Recommended value

FUSE (required)

2A/300V, slow-blow

MOV

S14K350

CY1

1.0nF/400Vac

CX

0.1µF/310Vac

LDM

Note:

1. Many safety standards require a bleeder resistor no greater than 3.8MΩ in parallel with the X-capacitor.

2. R1 must be a wire-wound resistor; do not use a chip or carbon film resistor.
