Bypass capacitor basics
A bypass capacitor (aka “filter cap”) is a small capacitor that dampens electrical noise moving toward an IC. Electrical noise can cause circuit malfunctions. Unless otherwise specified in the data sheet of an IC, a 0.1 µF non-polarized ceramic capacitor usually makes a good bypass capacitor.
