Please make sure to use a fuse of 0.5A
Capacitance : 3.3 to 22µF
Rated voltage : 250V or higher
Capacitance : 0.1 to 0.22µF Rated voltage : 250V or higher
Use a film or ceramic capacitor and evaluate characteristics under actual
operating conditions.
Capacitance : 100 to 470µF Rated voltage : 25V or higher
Impedance is 0.39Ω max at high frequency range.
Ripple current is 0.1Arms above.
Capacitor impedance affects the output ripple voltage.
In the absolute maximum ratings, the reverse surge voltage should be
400V or higher, the average rectifying current should be 0.5A or higher,
and the forward surge current 20A or higher.
10 to 22Ω, 1/4W
Use for terminal voltage noise reduction. Determine the optimal value
through actual testing.
A varistor must be used to protect the part against lightning surges and
static electricity.
