The electric susceptibility χ e of a dielectric materials is a measure of how easily it polarizes in response to an electric field. This, in turn, determines the electric permittivity of the material and thus influences many other phenomena in that medium, from the capacitance of capacitors to the speed of light.. It is defined as the constant of proportionality (which may be a tensor

The Clausius–Mossotti relation is named after the Italian physicist Ottaviano-Fabrizio Mossotti, whose 1850 book [1] analyzed the relationship between the dielectric constants of two different media, and the German physicist Rudolf Clausius, who gave the formula explicitly in his 1879 book [2] in the context not of dielectric constants but of indices of refraction.

X7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials. X7R is the most popular of these intermediate dielectric constant materials. Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change is non-linear.


Values presented here are relative dielectric constants (relative permittivities). As indicated by e r = 1.00000 for a vacuum, all values are relative to a vacuum.. Multiply by ε 0 = 8.8542 x 10-12 F/m (permittivity of free space) to obtain absolute permittivity. Dielectric constant is a measure of the charge retention capacity of a medium.
