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
Use a quick-acting fuse of 0.5A
C1: Input smoothing
capacitor
Capacitance : 3.3 to 22µF Rated voltage : 200V or higher
Ripple current is 0.13Arms or above.
C2: Noise reduction
capacitor
Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.
C3: Output smoothing
capacitor
Capacitance : 100 to 470µF Rated voltage : 50V or higher,
ESR is 0.39 max. Ripple current is 0.1Arms or greater.
Evaluate under actual operating conditions.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the forward peak 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.
