Standard X7R MLCC
Standard X7R Dielectric
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 conditions such as volt-
age and frequency.
X7R dielectric chip usage covers the broad spectrum of industrial applications where known
changes in capacitance due to applied voltages are acceptable.
