Be sure to use fuse for safety.
Please verify operation and characteristics in the customer's circuit before actual usage and ensure
that the load current does not exceed 200mA.
External Component Specifications
FUSE: Fuse
Use a fuse of 0.5A
C1: Input smoothing
capacitor
Capacitance : 4.7 to 22µF Rated voltage : 200V or higher
Ripple current is 0.13Arms or above.
C2: Noise reduction
capacitor
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 : 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.
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.
D1: Rectifier diode
L1: Choke coil
Coil for switching regulator. The inductance should be 1mH,
the rated direct current should be 0.18A or above in order to prevent
overheating or abnormal oscillation.
R1: Noise reduction
resistor
ZNR: Varistor
Load Regulation
Surface Temperature Increase
Surface Temperature Increase
10 to 22Ω, 1/4W
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
