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 greater.
C2: Noise reduction
capacitor
Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher
Use a film or ceramic capacitor. Evaluate under actual
conditions.
C3: Output smoothing
capacitor
Capacitance : 100 to 470µF Rated voltage : 25V or higher,
ECR is 0.4Ω max. Ripple current is 0.25Arms or higher.
Evaluate under actual operating conditions.
D1: Rectifier diode
L1: Choke coil
R1: Noise reduction
resistor
ZNR: Varistor
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 20A or higher.
(Full-wave rectification can be used.)
Coil for switching regulator. The inductance should be 1mH,
the rated direct current should be 0.6A or greater in order to prevent
overheating or abnormal oscillation.
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and
static electricity.
