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 2A
C1: Input smoothing
capacitor
Capacitance : 22 to 47µF Rated voltage : 200V or higher
Ripple current is 0.22Arms or greater.
C2: Noise reduction
capacitor
Capacitance : 0.1µF to 0.22µF Rated voltage : 200V or higher
Use a film or ceramic capacitor. Evaluate under actual
operating conditions.
C3: Output smoothing
capacitor
Capacitance : 220µF to 820µF Rated voltage : 25V or higher,
ESR is 0.15Ω max. Ripple current is 1.0Arms or greater.
Evaluate under actual operating conditions.
D1: Rectifier diode
L1: Choke coil
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the peak surge current should be 40A or higher.
(Full-wave rectification can be used.)
Coil for switching regulator. The inductance should be 470µH,
the rated direct current should be 1.0A or greater in order to prevent
overheating or abnormal oscillation.
R1: Noise reduction
resistor
ZNR: Varistor
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
