Outside part F1: FUSE C1: Input capacitor Use a fuse for safety. Rated voltage : More than 50V Capacity : more than 100F, low impedance type Rated ripple current : More than 0.2Arms Rated voltage : More than 10V Capacity : 220 to 680F, low impedance type Rated ripple current : More than 0.2Arms Evaluate it with the actual opportunity because it influences an output ripple voltage.
