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 temperature varia-

tion 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 op-

erating conditions such as voltage and frequency.

X7R dielectric chip usage covers the broad spectrum of

industrial applications where known changes in capacitance

due to applied voltages are acceptable.
