What is a decoupling capacitor and how do I know if I need one?

Often the datasheet for the chip specifically calls out how many and what size capacitors to use. If it doesn''t, best practice is to attach a 1 uF cap to the power pins of each chip, plus a larger cap somewhere on the board. (Before 2001, best practice used 0.1 uF caps).

Understanding Chip Capacitors

Capacitors are electrical energy storage devices used in the electronics circuits for varied applications notably as elements of resonant circuits, in coupling and by-pass application, blockage of DC current, as high frequency impedance matching and timing elements, as filters in delay-line components, and in voltage transient suppression.

Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
