Capacitance : 22µF~820µF Rated voltage : 400V or higher
Ripple current is 0.13Arms above.
Capacitance : 0.1µF~0.22µF Rated voltage : 400V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
Capacitance : 100µF~470µF Rated voltage : 35V or higher,
ESR is 0.4Ω max. Ripple current is 0.25Arms above.
Output noise voltage is infulenced.Please evaluate it in the actual set.
L : 1.5mH Allowable current : 400mA ot 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
800V 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 out part.)
10Ω~22Ω 1/4W
Reduce the noise terminal voltage.Please set it,if necessary.
The constant value should be evaluated in set.
Varistor must be used. It protects this part from lightning surge and static
electricity.
