Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
High Temperature 150°C, X8L Dielectric, 10 – 50 VDC
(Commercial & Automotive Grade)
Overview
KEMET’s X8L dielectric features a 150°C maximum operating
temperature and is considered “general purpose high
temperature.” These components are fixed, ceramic dielectric
capacitors suited for high temperature bypass and decoupling
applications or frequency discriminating circuits where Q and
stability of capacitance characteristics are not critical. X8L
exhibits a predictable change in capacitance with respect to time
and voltage and boasts a minimal change in capacitance with
reference to ambient temperature up to 125°C. Beyond 125°C
X8L displays a wider variation in capacitance. Capacitance
change is limited to ±15% from −55°C to +125°C and +15, -40%
from 125°C to 150°C.
stress to the rigid ceramic body, therefore mitigating flex cracks
which can result in low IR or short circuit failures. Although
flexible termination technology does not eliminate the potential
for mechanical damage that may propagate during extreme
environmental and handling conditions, it does provide superior
flex performance over standard termination systems.
In addition to commercial grade, automotive grade devices
are available and meet the demanding Automotive Electronics
Council's AEC–Q200 qualification requirements.
Driven by the demand for a more robust and reliable
component, X8L dielectric capacitors were developed for critical
applications where reliability at higher operating temperatures
are a concern. These capacitors are widely used in automotive
circuits as well as general high temperature applications.
Concerned with flex cracks resulting from excessive tensile
and shear stresses produced during board flexure and thermal
cycling? These devices are available with KEMET's Flexible
termination technology which inhibits the transfer of board
