External Component Specifications
FUSE: Fuse
Use a fuse of 0.5A
Capacitance : 3.3 to 22µF Ripple current is 0.13Arms or above.
Rated voltage : 200V or higher
Capacitance : 0.1 to 0.22µF Rated voltage : 200V or higher
Use a film or ceramic capacitor. Evaluate under actual operating conditions.
Capacitance : 100 to 470µF Rated voltage : 25V or higher, low impedance
Impedance is 0.39Ω max at high frequencies.
Ripple current is 0.1Arms or above.
Capacitance 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 should be 20A or higher.
10 to 22Ω 1/4W
Determine the ideal value through actual testing.
A varistor must be used to protect against lightning surges and static
electricity.
