voltage smoothing
Please make sure to use fuse 1.0A
Capacitance : 3.3碌F to 33碌F
Rated voltage : 250V or higher
Capacitance : 47碌F to 470碌F
Rated voltage : 16V or higher, Low impedance part
Impedance is 0.42鈩?max at High frequency range.
Ripple current is 0.2Arms above.
Impedance of capacitor affects the output ripple voltage.
Capacitance : 0.1碌F to 0.22碌F Rated voltage : 250V or higher
Film capacitor or ceramic capacitor. Reduce the noise terminal voltage.
The constant value should be evaluated in the set.
In the absolute maximum ratings, the reverse peak voltage should be
400V or higher, the average rectifying current should be 1A or higher,
and the forward surge current should be 40A or higher.
10鈩?to 22鈩?1/4W
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.
