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.
External components setting
FUSE: Fuse
C1: Capacitor for input
voltage smoothing
C2: Capacitor for Output
voltage smoothing
C3: For noise terminal
voltage reduction
Please make sure to use fuse 1.0A
Capacitance : 3.3µF to 33µF
Rated voltage : 250V or higher
Capacitance : 47µF to 470µF
Rated voltage : 16V or higher, Low impedance part
Impedance is 0.42Ω max at High frequency range.
Ripple current is 0.2Arms above.
Impedance of capacitor affects the output ripple voltage.
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.
D1: Rectifier diode
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the forward surge current should be 40A or higher.
R1: For noise terminal
voltage reduction
10Ω to 22Ω 1/4W
Reduce the noise terminal voltage.
The constant value should be evaluated in set.
ZNR: Varistor
Varistor must be used. It protects this part from lightning surge and static
electricity.
