C0G (NP0) Dielectric
General Specifications
C0G (NP0) is the most popular formulation of the “tempera-
ture-compensating,” EIA Class I ceramic materials. Modern
C0G (NP0) formulations contain neodymium, samarium and
other rare earth oxides.
C0G (NP0) ceramics offer one of the most stable capacitor
dielectrics available. Capacitance change with temperature
is 0 30ppm/°C which is less than 0.3% ∆ C from -55°C
to +125°C. Capacitance drift or hysteresis for C0G (NP0)
ceramics is negligible at less than 0.05% versus up to
2% for films. Typical capacitance change with life is less
than 0.1% for C0G (NP0), one-fifth that shown by most
other dielectrics. C0G (NP0) formulations show no aging
characteristics.
The C0G (NP0) formulation usually has a “Q” in excess
of 1000 and shows little capacitance or “Q” changes with
frequency. Their dielectric absorption is typically less than
0.6% which is similar to mica and most films.
