The KEMET Automotive Grade Surface Mount Capacitors
in X7R dielectric are suited for a variety of applications
requiring proven, reliable performance in harsh
environments.
Whether underhood or in-cabin, these
devices emphasize the vital and robust nature of capacitors
required for mission and safety of critical automotive
circuits.
Stricter testing protocol and inspection criteria
have been established for automotive grade products in
recognition of potentially harsh environmental conditions.
- KEMET automotive grade capacitors meet the demanding
Automotive Electronics Council's AEC-Q200 qualification
requirements.
X7R dielectric features a 125°C maximum operating
temperature and is considered temperature stable.
- The
Electronics Industries Alliance (EIA) characterizes X7R
dielectric as a Class II material.
- Components of this
classification are fixed, ceramic dielectric capacitors, suited
for bypass and decoupling applications, or for frequency
discriminating circuits, where Q and stability of capacitance
characteristics are not critical.
- X7R exhibits a predictable
change in capacitance with respect to time and voltage,
and boasts a minimal change in capacitance with reference
to ambient temperature. Capacitance change is limited to
±15% from −55°C to +125°C.
