I am looking for a simple PCB board to handle incoming 5v power supply

I am looking for a simple PCB board to handle incoming 5v power supply to have capacitor and/or fuse to stop power spikes.
Currently just soldering on a capacitor to the power line, but be dammed someone should have something somewhere.

What capacitor? 10µF, 100µF(electrolytic)? Try these values or something in between for starters.
