1210Cxxxx fiche technique
XGe7nReraDl Sipeelceifcict4taUrtii.occnosm X7R formulations are called “temperature stable” ceramics
and fall into EIA Class II materials. X7R is the most popular
e of these intermediate dielectric constant materials. Its tem-
he perature variation of capacitance is within ±15% from
-55°C to +125°C. This capacitance change is non-linear.
taS Capacitance for X7R varies under the influence of electrical
a operating conditions such as voltage and frequency.
.D X7R dielectric chip usage covers the broad spectrum of
industrial applications where known changes in capaci-
w tance due to applied voltages are acceptable.
