KEMET’s High Voltage surface mount MLCCs in C0G
dielectric are temperature compensating and are suited for
resonant circuit applications or those where Q and stability
of capacitance characteristics are required. C0G exhibits
no change in capacitance with respect to time and voltage
and boasts a negligible change in capacitance with
reference to ambient temperature. Capacitance change is
limited to ±30ppm/°C from −55°C to +125°C.
These devices exhibit low ESR at high frequencies and
find conventional use as snubbers or filters in applications
such as switching power supplies and lighting ballasts.
Their exceptional performance at high frequencies has
made C0G high voltage the preferred dielectric choice of
design engineers worldwide. In addition to Commercial
Grade, Automotive Grade devices are available which meet
the demanding Automotive Electronics Council’s
AEC–Q200 qualification requirements.
