FUSE: Fuse Please make sure to use quick acting fuse 0.5A
Capacitance(C1,2) : 0.1µF to 0.22µF, (C4): 4700pF degree
Rated voltage : 200V or higher. Film capacitor or ceramic capacitor.
Reduce the noise terminal voltage.The constant value should be evaluated
in the set.
C1,2,4 : For noise terminal
voltage reduction
Capacitance : 33µF to 330µF Rated voltage : 200V or higherC3: Capacitor for input
voltage smoothing
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the peak surge current should be 20A or higher.
(Full-wave rectifier can be used in our part.)
D1: Rectifier diode
Capacitance : 470µF to 1000µF Rated voltage : 16V or higher,
ESR is 0.16Ω max. Ripple current is 0.58Arms above.
Output noise voltage is influenced.Please evaluate it in the actual set.
C5: Capacitor for Output
voltage smooting
Please use the linefilter, if necessary.
FL1: For noise terminal
voltage reduction
ZNR: Varistor Varistor must be used. It protects this part from lightning surge and
static electricity.
