X7S Dielectric, KGM Series
General Specifications
GENERAL DESCRIPTION
X7S formulations are called “temperature stable” ceramics and fall into EIA Class II materials. Its temperature
variation of capacitances within ±22% from –55°C to +125°C. This capacitance change is non-linear.
Capacitance for X7S varies under the influence of electrical operating conditions such as voltage and frequency.
X7S dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance
due to applied voltages are acceptable.
