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 : 33 to 100µF Rated voltage : 200V or higher
Ripple current is 0.13Arms or above.
C2: Noise reduction
resistor
Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher
Use a film or ceramic capacitor. Evaluate under actual operating
conditions.
C3: Output smoothing
capacitor
D1: Rectifier diode
Capacitance : 220 to 470µF Rated voltage : 16V or higher,
ESR is 0.4Ω max. Ripple current is 0.25Arms or 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 should be 20A or higher.
(Full-wave rectification can be used.)
L1: Choke coil
R1: Noise reduction
resistor
Coil for switching regulator. The inductance should be 470µH,
the rated direct current should be 0.9A or above in order to prevent
overheating and abnormal oscillation.
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.
