Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
Capacitance : 100碌F鈭?70碌F 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.
L : 1mH Allowable current : 600mA or higher
Please use the one that is hard to be magnetic saturated even in the high
temperature.
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.)

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.
