X7S Dielectric
General Specifications
GENERAL DESCRIPTION
X7S formulations are called “temperature stable” ceramics and fall
into EIA Class II materials. Its temperature variation of capacitance
is within ±±±2 from –55°C to +1±5°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.
