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 : 250V or higher
Ripple current is 0.13Arms or above.
C2: Noise reduction
capacitor
Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher
Use a film or ceramic capacitor. Evaluate under actual conditions.
C3: Output voltage
smoothing capacitor
D1: Rectifier diode
Capacitance : 100 to 470µF Rated voltage : 25V or higher,
ESR is 0.39Ω max. Ripple current is 0.1Arms above.
Evaluate under actual operating conditions.
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 peak surge current 20A or greater.
(Full-wave rectification can be used)
R1: Noise reduction
resistor
ZNR: Varistor
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor must be used to protect against lighting surges and static
electricity.
