MULTILAYER CERAMIC CAPACITORS/AXIAL & RADIAL LEADED

Multilayer ceramic capacitors are available in a
variety of physical sizes and configurations, including
leaded devices and surface mounted chips. Leaded
styles include molded and conformally coated parts
with axial and radial leads. However, the basic
capacitor element is similar for all styles. It is called a
chip and consists of formulated dielectric materials
which have been cast into thin layers, interspersed
with metal electrodes alternately exposed on opposite

edges of the laminated structure.

The entire structure is
fired at high temperature to produce a monolithic
block

which provides high capacitance values in a
small physical volume. After firing, conductive
terminations are applied to opposite ends of the chip to
make contact with the exposed electrodes.
Termination materials and methods vary depending on
the intended use.

TEMPERATURE CHARACTERISTICS

Ceramic dielectric materials can be formulated with
a wide range of characteristics. The EIA standard for
ceramic dielectric capacitors (RS-198) divides ceramic
dielectrics into the following classes:

Class I: Temperature compensating capacitors,
suitable for resonant circuit application or other appli­cations where high Q and stability of capacitance char­acteristics are required. Class I capacitors have
predictable temperature coefficients and are not
effected by voltage, frequency or time. They are made
from materials which are not ferro-electric, yielding
superior stability but low volumetric efficiency. Class I
capacitors are the most stable type available, but have
the lowest volumetric efficiency.

Class II: Stable capacitors, suitable for bypass
or coupling applications or frequency discriminating
circuits where Q and stability of capacitance char­acteristics are not of major importance. Class II
capacitors have temperature characteristics of ± 15%
or less. They are made from materials which are
ferro-electric, yielding higher volumetric efficiency but
less stability. Class II capacitors are affected by
temperature, voltage, frequency and time.

Class III: General purpose capacitors, suitable
for by-pass coupling or other applications in which
dielectric losses, high insulation resistance and
stability of capacitance characteristics are of little or
no importance. Class III capacitors are similar to Class
II capacitors except for temperature characteristics,
which are greater than ± 15%. Class III capacitors
have the highest vol

umetric efficiency and poorest

stability of any type.

KEMET leaded ceramic capacitors are offered in
the three most popular temperature characteristics:

C0G: Class I, with a temperature coefficient of 0 ±

30 ppm per degree C over an operating

temperature range of - 55°C to + 125°C (Also

known as “NP0”).

X7R: Class II, with a maximum capacitance

change of ± 15% over an operating temperature

range of - 55°C to + 125°C.

Z5U: Class III, with a maximum capacitance

change of + 22% - 56% over an operating tem-

perature range of + 10°C to + 85°C.

Specified electrical limits for these three temperature
characteristics are shown in Table 1.
