FUSE: Fuse Please make sure to use quick acting fuse 1A
Capacitance : 22µF∼820µF Rated voltage : 250V or higher
Ripple current is 0.13Arms above.
Capacitance : 0.1µF∼0.22µF Rated voltage : 25V 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∼470µF Rated voltage : 250V or higher,
ESR is 0.4W max. Ripple current is 0.25Arms above.
Output noise voltage is influenced. Please evaluate it in the actual set.
C3: Capacitor for Output
voltage smooting
L : 1mH Allowable current : 600mA or higher
Please use the one that is hard to be magnetic saturated even in the high
temperature.
L1: Choke coil
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
10Ω∼22Ω 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 lightning surge and static
electricity.
ZNR: Varistor
