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 1A
C1: Input smoothing
capacitor
Capacitance : 22 to 100µF 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 : 25V or higher,
ESR is 0.25Ω max. Ripple current is 0.4Arms or above.
Evaluate under actual 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 peak surge current should be 20A or higher.
(Full-wave rectification can be used)
L1: Choke coil
Coil for switching regulator. The inductance should be 820µH,
the rated direct current should be 0.42A or above
in order to prevent excessive heat generation or oscillation.
R1: Noise reduction
resistor
10 to 22Ω 1/4W
The ideal value can be determined through actual testing.
ZNR: Varistor
A varistor must be used to protect against lightning surges and static electricity.
