Be sure to use fuse for safety.
For actual usage, Please kindly evaluate and confirm our part mounted in your product,
Especially, Please make sure to confirm whether the load current exceed Max. rated current
by using the current probe.

FUSE: Fuse
C1: Capacitor for input
voltage smoothing
C2: For noise terminal
voltage reduction
C3: Capacitor for Output
voltage smoothing
D1: Rectifier diode
R1: For noise terminal

ZNR: Varistor
Please make sure to use fuse 0.5A
Capacitance : 3.3µF to 22µF
Rated voltage : 250V or higher
Capacitance : 0.1µF to 0.22µF Rated voltage : 250V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
Capacitance : 100µF to 470µF Rated voltage : 25V or higher, Low impedance part
Impedance is 0.39Ω max at high frequency range.
Ripple current is 0.1Arms above.
Impedance of capacitor 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.
10Ω to 22Ω, 1/4W
Reduce the noise terminal voltage. The constant value should be evaluated
in set.
Varistor must be used. It protects this part from lightning surge and static
electricity.
