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.
