How to Choose a Bypass Capacitor Size
When placing a bypass capacitor in any standard PCB, it should generally be located as close to the IC pin as possible. The larger the distance between the capacitor and power pin, the more the inductance increases, which severely decreases the signal quality. The signal quality is also heavily dependent on the bypass capacitor size.
8.2: Capacitors and Capacitance
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.")
18.5: Capacitors
Capacitors are common electronic devices that are used to store electric charge for a variety of applications. A capacitor is usually constructed with two conducting plates (called "terminals" or "electrodes") separated by either air or an insulating material.

0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of ...

19.5: Capacitors and Dielectrics
The unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or
5.22: Capacitance
A capacitor is a device that is designed to exhibit a specified capacitance. We can now make the connection to the concept of the capacitor as it appears in elementary circuit theory. In circuit theory, the behavior of devices is characterized in terms of terminal voltage (V_T) in response to terminal current (I_T), and vice versa.
6.1.2: Capacitance and Capacitors
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor.

Chapter 5 Capacitance and Dielectrics
A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1). Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with
