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 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 con-
ditions 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.
