X8R/X8L Dielectric
General Specifications
www.DataSheet4U.com
AVX has developed a range of multilayer ceramic capacitors designed for use in applications up to 150ºC.
These capacitors are manufactured with an X8R and an X8L dielectric material. X8R material has
capacitance variation of ±15% between -55ºC and +150ºC. The X8L material has capacitance variation of
±15% between -55ºC to 125ºC and +15/-40% from +125ºC to +150ºC.
The need for X8R and X8L performance has been driven by customer requirements for parts that operate
at elevated temperatures. They provide a highly reliable capacitor with low loss and stable capacitance
over temperature.
They are ideal for automotive under the hood sensors, and various industrial applications. Typical industrial
application would be drilling monitoring system. They can also be used as bulk capacitors for high
temperature camera modules.
Both X8R and X8L dielectric capacitors are automotive AEC-Q200 qualified. Optional termination systems, tin,
FLEXITERM® and conductive epoxy for hybrid applications are available. Providing this series with our
FLEXITERM® termination system provides further advantage to customers by way of enhanced resistance to
both, temperature cycling and mechanical damage.
