The typical temperature range for ceramic capacitors is 40 to 85 c or 125 c where their capacitance varies about from 5 to 40 having a sweet spot around 5 to 25 c.

Ceramic capacitance vs voltage.

Capacitance of ceramic capacitors may also change with applied voltage. Class 2 ceramic capacitors also exhibit a logarithmic decrease in capacitance over time which is referred to as aging. Its temperature variation of capacitance is within 15 from 55 c to 125 c. The capacitance is often described in the product description as nominal value please note that among ceramic capacitors the capacitance especially of capacitors classified as high dielectric constant b x5r r x7r characteristic may differ from the nominal value when a dc voltage is applied.

A second interesting point is that within a package size and ceramic type the voltage rating of the capacitors seems often to have no effect. Capacitance measured or applied with higher voltage can drop to values of 80 of the value. X7r is the most popular of these intermediate dielectric constant materials. The higher the applied voltage the lower the permittivity.

Degradation of the polarized domains in these ferroelectric dielectrics decreases permittivity over time. Ceramic capacitors are brittle and sensitive to thermal shock so precautions need to be taken to avoid cracking during mounting especially for high capacitance large sizes. Capacitance change over voltage for a class 2 x5r ceramic capacitor. Dc and ac voltage dependence of ceramic capacitors introduction when selecting a ceramic capacitor it may seem as simple as choosing the device that offers the highest capacitance per unit volume at the lowest cost but one also needs to consider that the electrical response of.

X7r formulations are called temperature stable ceramics and fall into eia class ii materials. The ferroelectric material depends on the applied voltage. Voltage coefficient x5r mlcc 4 7uf x5r 4v 6 3v unstable over vdc x5r dielectric is most popular for high capacitance 1 uf mlccs in small sizes 4v and 6 3v ratings are common today exhibit large capacitance value decrease under applied vdc 2vdc applidlied can resullt iin 3545 35 45 capaciitance vallue ddecrease. This capacitance change is non linear.

The capacitance change in ceramic capacitors can also be caused by ac voltage. Note first that as the package size increases the capacitance variation with applied dc voltage decreases and substantially.
