X8R/X8L Dielectric
General Specifications
AVX has developed a range of multilayer ceramic capacitors designed for use in applications up to 150°C. These capacitors
are manufactured with an X8R and an X8L dielectric material. X8R material has capacitance variation of ± 15% between
-55°C and +150°C. The X8L material has capacitance variation of ±15% between -55°C to 125°C to 125°C and +15/40%
from +125°C to +150°C.
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.
