1812xxxx fiche technique
CGe0neGral(NSpPec0if)ict4DaUtii.oecnolsmectric C0G (NP0) is the most popular formulation of the “tempera-
ture-compensating,” EIA Class I ceramic materials. Modern
e C0G (NP0) formulations contain neodymium, samarium and
he other rare earth oxides.
S C0G (NP0) ceramics offer one of the most stable capacitor
ta dielectrics available. Capacitance change with temperature
a is 0 ±30ppm/°C which is less than ±0.3% C from -55°C
to +125°C. Capacitance drift or hysteresis for C0G (NP0)
.D ceramics is negligible at less than ±0.05% versus up to
w ±2% for films. Typical capacitance change with life is less
w than ±0.1% for C0G (NP0), one-fifth that shown by most
other dielectrics. C0G (NP0) formulations show no aging
w characteristics.
mThe C0G (NP0) formulation usually has a “Q” in excess
of 1000 and shows little capacitance or “Q” changes with
ofrequency. Their dielectric absorption is typically less than
.c0.6% which is similar to mica and most films.
