C0G (NP0) Dielectric
General Specifications
C0G (NP0) is the most popular formulation of the “temperature-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.
