FUSE:
Please make sure to use fuse 0.5A
Capacitance : 3.3µF to 22µF Ripple current is 0.13Arms above.
Rated voltage : 200V or higher
Capacitance : 0.1µF to 0.22µF Rated voltage : 200V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
C1 : Capacitor for input
voltage smoothing
C2 : For noise terminal
voltage reduction
Capacitance : 100µF to 470µF Rated voltage : 25V or higher, Low impedance part
Impedance is 0.39 max at High frequency range.
Ripple current is 0.1Arms above.
Impedance of capacitor affects the output ripple voltage.
C3 : Capacitor for Output
voltage smoothing
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
10~22 1/4W
Reduce the noise terminal voltage. The constant value should be evaluated
in set.
R1 : For noise terminal
voltage reduction
Varistor must be used. It protects this part from lighting surge and static
electricity.
