The Electronics Components, Assemblies & Materials Association (EIA) characterizes C0G dielectric as a Class I material.
Components of this classification are temperature compensating. Typically they are used 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 or voltage while exhibiting a negligible change in capacitance with reference to ambient temperature.
Capacitance change is limited to ±30 ppm/ºC from -55°C to +125°C. For more information about EIA Classifications, see this FAQ on Temperature Coefficients.
C0G capacitors are sometimes called “NPO” or “NP0”.
