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.

The multilayer ceramic capacitor and leaded film capacitor show roughly the same characteristics up to the resonance point, but the self-resonant frequency is higher and |Z| in the inductive region is lower in the multilayer ceramic capacitor. This is because, in leaded film capacitors, the inductance is only as large as that due to the lead wire.
