Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage.
Ensure that the load current does not exceed the maximum rating.
External Component Specifications
FUSE: fuse
C1: Input smoothing
capacitor
C2: Noise reduction
capacitor
Use a quick-acting fuse of 0.5A
Capacitance : 3.3µF to 22µF
Rated voltage : 250V or higher
Capacitance : 0.1µF to 0.22µF
Rated voltage : 250V or higher
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.
Capacitance : 100µF to 470µF
Rated voltage : 35V or higher, low impedance
Impedance is 0.39Ω max. at high frequencies.
Ripple current 0.1 Arms or greater.
Capacitor impedance affects the output ripple voltage.
In the absolute maximum ratings, the reverse surge voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the forward surge current should be 20A or higher.
10Ω to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
