Use a fuse for safety.
Rated voltage : More than 50V
Capacity : more than 100µF, low impedance type
Rated ripple current : More than 0.2Arms
Rated voltage : More than 10V
Capacity : 220 to 680µF, low impedance type
Rated ripple current : More than 0.2Arms
Evaluate it with the actual opportunity because
it influences an output ripple voltage.
