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
C1: Input smoothing
capacitor
Use a quick-acting fuse of 0.5A
Capacitance : 3.3 to 22µF
Rated voltage : 250V or higher
C2: Noise reduction
capacitor
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
Capacitance : 100 to 470µF
Rated voltage : 25V or higher, low impedance
Impedance is 0.39Ω max at high frequencies
Ripple current is 0.1Arms or above.
Capacitor impedance affects the output ripple voltage.
D1: Rectifier diode
In the absolute maximum ratings, the reverse surge voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the forward surge current should be 20A or higher.
R1: Noise reduction
resistor
10 to 22Ω, 1/4W
The ideal value should be determined through actual testing.
ZNR: Varistor
A varistor must be used to protect against lightning surges and
static electricity.
