X7R Dielectric

General Specifications

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 tem-

perature variation of capacitance is within 15% from

-55°C to +125°C. This capacitance change is non-linear.

Capacitance for X7R varies under the influence of electrical

operating conditions such as voltage and frequency.

X7R dielectric chip usage covers the broad spectrum of

industrial applications where known changes in capaci-

tance due to applied voltages are acceptable.
