High Reliability Chip - C0G
16Vdc to 10kVdc
A range of MLC chip capacitors in Ultra stable EIA Class I C0G, or
NP0, dielectric with special testing for long term reliability. They
are designed for optimum reliability; burned in at elevated voltage
and temperature, and 100% physically and electrically inspected
to ascertain conformance to strict performance criteria. Units may
be tested in accordance with MIL-PRF-55681, MIL-PRF-123, MIL-
PRF-49467, or customer SCD.
Designed for surface mount application with nickel barrier
terminations making them suitable for solder wave and reflow
solder board attachment as well as vapor phase attachment for
part sizes 2225 or smaller. Silver-palladium terminations are also
available for hybrid use with conductive epoxy.
C0G chips are used in precision circuitry requiring Class I stability
and exhibit linear temperature coefficient, low loss and stable
electrical properties with time, voltage & frequency.
They find application for High Reliability use such as medical
implanted devices, aerospace, airborne and military use as well
as consumer uses requiring safety margins not attainable with
commercial products.
Standard EIA case sizes and available C/V values are listed below
- special sizes, thicknesses and other voltage ratings are available;
please contact the sales office for information.
