Guide to Ceramic Capacitor Dielectrics and Other Types
The strength of the electric field in the capacitor dielectric determines how displacement current arises through the device, thus we can categorize capacitors based on their insulating dielectric. In this article, we discuss the categorization of capacitor dielectrics, including a section dedicated to ceramic capacitor dielectrics.

A parallel plate capacitor with a dielectric between its plates has a capacitance given by (C=kappa varepsilon _{0} dfrac{A}{d},) where (kappa) is the dielectric constant of the material. The maximum electric field strength above which an insulating material begins to break down and conduct is called dielectric strength.
