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.
