COG
(NPO) Dielectrics
are considered to be
“ultra stable” ceramics
that fall into the category of Class I dielectrics as defined
by
EIA-198.
They are characterized
by a near linear temperature coefficient,
are non piezoelectric,
exhibit low loss, no
aging and negligible
performance variation
due to
changes in working voltage and
frequency. Our
proprietary dielectric material
formulations achieve “best in class”
dissipation factor levels, excellent volumetric efficiency and dielectric
breakdown characteristics,
while maintaining stable performance
attributes related to
variations in time, temperature, applied
voltage and frequency.
Typical
applications
include
precision
timing
circuits, oscillators and other
precision circuitry requiring
low loss and stable
performance.
