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.

High Voltage Chips
For 500V to 5000V Applications
High value, low leakage and small size are difficult parameters to obtain
in capacitors for high voltage systems. AVX special high voltage MLC
chips capacitors meet these performance characteristics and are
designed for applications such as snubbers in high frequency power
converters, resonators in SMPS, and high voltage coupling/DC blocking.
These high voltage chip designs exhibit low ESRs at high frequencies.
Larger physical sizes than normally encountered chips are used to
make high voltage chips. These larger sizes require that special pre-
cautions be taken in applying these chips in surface mount assem-
blies. This is due to differences in the coefficient of thermal expansion
(CTE) between the substrate materials and chip capacitors. Apply heat
at less than 4°C per second during the preheat. Maximum preheat
temperature must be within 50°C of the soldering temperature.
The solder temperature should not exceed 230°C. Chips 1808 and
larger to use reflow soldering only.
Capacitors with X7R Dielectrics are not intended for AC line filtering
applications.
Contact plant for recommendations. Capacitors may require protective
surface coating to prevent external arcing.
