Fundamentals | Capacitor Guide
The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses. The Q factor is not a constant value and changes significantly with frequency. Although most applications do not have to take the Q factor into serious consideration, and standard capacitors may be used in those ...
Dissipation factor
The loss tangent is defined by the angle between the capacitor''s impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or

Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
