External Component Specifications
FUSE: Fuse
Use a quick-acting fuse of 0.5A
C1: Input smoothing
capacitor
Capacitance : 3.3 to 22µF Rated voltage : 450V or higher
Ripple current is 0.13Arms or greater.
C2: Noise reduction
resistor
Capacitance : 0.1 to 0.22µF Rated voltage : 400V or higher
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.

ESR is 0.39Ω max. Ripple current is 0.1Arms or higher.
Evaluate under actual operating conditions.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
800V or higher, the average rectifying current should be 0.5A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectification can be used.)
R1: Noise reduction
resistor
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
ZNR: Varistor
A varistor is required to protect against lightning surges and static
electricity.
