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 fuse of 1A
C1: Input smoothing
capacitor
C2: Noise reduction
capacitor
Capacitance : 22µF
Ripple current is 0.13Arms or above.
Rated voltage : 200V or higher
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 : 16V or higher, low impedance
Impedance is 0.4Ω max at high frequencies.
Ripple current 0.25Arms or above.
Capacitor impedance affects the output ripple voltage.
D1: Rectifier diode
L1: Power inductor
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.
Inductance : 470µH, Rating current : above 0.57A
Select components that do not easily become magnetically saturated
at high temperatures.
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.
