A dielectric material is used to separate the conductive plates of a capacitor. This insulating material significantly determines the properties of a component. The dielectric constant of a material determines the amount of energy a capacitor can store when voltage is applied. A dielectric material becomes polarized when it is exposed to an electric field. When polarization occurs, the effective electric field is reduced.

Capacitors that rapidly store and release electric energy are key components in modern electronics and power systems. However, the most commonly used ones have low energy densities compared to other storage systems like batteries or fuel cells, which in turn cannot discharge and recharge rapidly without sustaining damage.

Class 2 capacitors can be divided in: those with a moderate temperature dependence (X7R or 2C1) and others that only a fraction of the capacitance remains at the temperature limits (Z5U or 2F4).
