Clean Power for Every IC, Part 2: Choosing and Using Your Bypass Capacitors
And this, in turn, demonstrates why the exact capacitance of a bypass capacitor is not particularly important: as long as the capacitor can store enough charge, the capacitance value is acceptable. It turns out that 0.1 µF is a convenient value, but 1 µF or even 0.01 µF might be equally appropriate in terms of capacitance .
Electrical noise is common in direct current digital circuits. The noise is primarily an AC signal that, if uncontrolled, will affect the flow of current. Hence, it is essential to eliminate it via the use of a ceramic capacitor. …

A typical value for such a capacitor is 10μF to 50μF (usually tantalum or electrolytic). The exact value is not critical as having a capacitor around this range is much better than not having one. Capacitors not only store energy, but they also filter out noise. Which brings me to decoupling capacitors for filtering out noise.

A capacitor which is used to link one circuit''s AC signal to another circuit is referred to as a coupling capacitor. Blocking the DC signal and allowing the AC signal from one circuit to another is the main feature of this capacitor.

Bypass capacitors serve two main functions, namely to short high-frequency noise to ground and to act as current reservoirs. Consequently there are three basic methods to fan-out power pins. The first method usually occurs when the autorouter is used to create the fan-outs automatically. The autorouter creates individual fan-out vias for the IC ...
