What capacitor parallell to Zenerdiode on servo rail?


Im having trouble figuring out what specs. to be for the recommended capacitor parallel to a zenerdiode when connecting a BEC to the servo rail on a pixhawk.

Wiki says “To complement the diode, it is also useful to add a capacitorin parallel to the diode. The capacitor will smooth out eventual voltage ripples. As advised for the diode, the capacitor should be connected with as short wires as possible. Do not oversize the capacitor.”

What are the recommended specs on the capacitor? (I have no idea what so ever!)

100uF ceramic capacitor should do fine.

Thanks a million :slight_smile: (late reply from me… Winter… Sucks…getting more sunny tho :slight_smile:)
