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
Please make sure to use a fuse of 0.5A
C1: Input smoothing
capacitor
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 and evaluate characteristics under actual
operating conditions.
C3: Capacitor for Output
voltage smoothing
D1: Rectifier diode
Capacitance : 100 to 470µF Rated voltage : 25V or higher
Impedance is 0.39Ω max at high frequency range.
Ripple current is 0.1Arms 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 20A or higher.
R1: Noise reduction
resistor
10 to 22Ω, 1/4W
Use for terminal voltage noise reduction. Determine the optimal value
through actual testing.
ZNR: Varistor
A varistor must be used to protect the part against lightning surges and
static electricity.
