STANDARD
CERAMIC CAPACITORS
General Information
Taping : dimensions NPO/COG (Class 1)
COMPOSITION
NPO capacitors are produced by using a dielectric made of titanium dioxide
(Ti O
2
) modified by magnesium oxide Mg O (white ceramics) or a rare earth
oxide, e.g. Nd
2
O
3
(other NPO ceramics).
As a consequence, these ceramics are non ferro-electric materials with a low
dielectric constant (
ε
r ≤ 110).
Other additives are used to dope the dielectric constant up to 300. Though der-
ogating from CG class, doped dielectric constant features a linear temperature
drift and a matchless stability compared with class 2 ceramics.
The wide range of possible NPO dielectric compositions enables to use the ma-
terial best suited to the application :
• standard applications,
• high voltage,
• high temperature,
• microwave,
• power capacitors.
«Temperature coefficient» compositions are particularly suitable for imped-
ance matching. These ceramics usually enable to achieve temperature coef-
ficients from 0 to –1 000 ppm/°C. For specific requirements, other coefficients
can be achieved (e.g. –3 300 ppm/°C).

STABILITY
As
ε
r is low, these dielectrics are extremely stable with only minor changes
under such stresses as :
• temperature,
• voltage,
• frequency.
In addition, they are not affected by piezo-electric phenomena and their dielec-
tric absorption coefficients are low and even non measurable for dielectrics
with the lowest constants.
MECHANICAL PROPERTIES
Class 1 ceramics are the perfect match for metallic electrodes made of Pd or
Ag-Pd alloy and have a high hardness and mechanical toughness making them
resistant to thermal shocks (wave soldering for instance) and to thermal cy-
cling after mounting on substrates having an expansion coefficient close to
the capacitor one.
Ceramic chips meet CECC 32100 and NF C 93133 standards.
CLIMATIC CATEGORIES
Climatic categories are identified by three-digit codes as per NF C 20700 stan-
dard. Coding method is described in table 6.
e.g. : – 55°C + 125°C / 56 days category is identified by code 434.
