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 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
Class I: Temperature compensating capacitors, II capacitors except for temperature characteristics,
suitable for resonant circuit application or other appli- which are greater than ± 15%. Class III capacitors
cations where high Q and stability of capacitance char- have the highest volumetric efficiency and poorest
acteristics are required. Class I capacitors have stability of any type.
predictable temperature coefficients and are not
affected 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.
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”).
Class II: Stable capacitors, suitable for bypass
X7R: Class II, with a maximum capacitance
or coupling applications or frequency discriminating
change of ± 15% over an operating temperature
circuits where Q and stability of capacitance char-
range of - 55°C to + 125°C.
acteristics are not of major importance. Class II
Z5U: Class III, with a maximum capacitance
capacitors have temperature characteristics of ± 15%
change of + 22% - 56% over an operating tem-
or less. They are made from materials which are
perature range of + 10°C to + 85°C.

APPLICATION NOTES FOR MULTILAYER
CERAMIC CAPACITORS
POWER DISSIPATION
Power dissipation has been empirically determined for
two representative KEMET series: C052 and C062. Power dis-
sipation capability for various mounting configurations is shown
in Table 3. This table was extracted from Engineering Bulletin
F-2013, which provides a more detailed treatment of this sub-
ject.
Note that no significant difference was detected between
the two sizes in spite of a 2 to 1 surface area ratio. Due to the
materials used in the construction of multilayer ceramic capac-
itors, the power dissipation capability does not depend greatly
on the surface area of the capacitor body, but rather on how
well heat is conducted out of the capacitor lead wires.
Consequently, this power dissipation capability is applicable to
other leaded multilayer styles and sizes.

As shown in Table 3, the power dissipation capability of
the capacitor is very sensitive to the details of its use environ-
ment. The temperature rise due to power dissipation should not
exceed 20°C. Using that constraint, the maximum permissible
power dissipation may be calculated from the data provided in
Table 3.
It is often convenient to translate power dissipation capa-
bility into a permissible AC voltage rating. Assuming a sinu-
soidal wave form, the RMS “ripple voltage” may be calculated
from the following formula:
E=Zx
PMAX
R
Where E = RMS Ripple Voltage (volts)
P = Power Dissipation (watts)
Z = Impedance
R = ESR
The data necessary to make this calculation is included in
Engineering Bulletin F-2013. However, the following criteria
must be observed:
1. The temperature rise due to power dissipation
should be limited to 20°C.
2. The peak AC voltage plus the DC voltage must not
exceed the maximum working voltage of the
capacitor.
Provided that these criteria are met, multilayer ceramic
capacitors may be operated with AC voltage applied without
need for DC bias.
RELIABILITY
A well constructed multilayer ceramic capacitor is
extremely reliable and, for all practical purposes, has an infi-
nite life span when used within the maximum voltage and
temperature ratings. Capacitor failure may be induced by sus-
tained operation at voltages that exceed the rated DC voltage,
voltage spikes or transients that exceed the dielectric with-
standing voltage, sustained operation at temperatures above
the maximum rated temperature, or the excessive tempera-
ture rise due to power dissipation.
Failure rate is usually expressed in terms of percent per
1,000 hours or in FITS (failure per billion hours). Some
KEMET series are qualified under U.S. military established
reliability specifications MIL-PRF-20, MIL-PRF-123, MIL-
PRF-39014, and MIL-PRF-55681. Failure rates as low as
0.001% per 1,000 hours are available for all capacitance /
voltage ratings covered by these specifications. These spec-
ifications and accompanying Qualified Products List should
be consulted for details.
For series not covered by these military specifications,
an internal testing program is maintained by KEMET Quality
Assurance. Samples from each week’s production are sub-
jected to a 2,000 hour accelerated life test at 2 x rated voltage
and maximum rated temperature. Based on the results of
these tests, the average failure rate for all non-military series
covered by this test program is currently 0.06% per 1,000
hours at maximum rated conditions. The failure rate would be
much lower at typical use conditions. For example, using MIL-
HDBK-217D this failure rate translates to 0.9 FITS at 50%
rated voltage and 50°C.
Current failure rate details for specific KEMET multilay-
er ceramic capacitor series are available on request.
MISAPPLICATION
Ceramic capacitors, like any other capacitors, may fail
if they are misapplied. Typical misapplications include expo-
sure to excessive voltage, current or temperature. If the
dielectric layer of the capacitor is damaged by misapplication
the electrical energy of the circuit can be released as heat,
which may damage the circuit board and other components
as well.
If potential for misapplication exists, it is recommended
that precautions be taken to protect personnel and equipment
during initial application of voltage. Commonly used precau-
tions include shielding of personnel and sensing for excessive
power drain during board testing.
STORAGE AND HANDLING
Ceramic chip capacitors should be stored in normal
working environments. While the chips themselves are quite
robust in other environments, solderability will be degraded
by exposure to high temperatures, high humidity, corrosive
atmospheres, and long term storage. In addition, packaging
materials will be degraded by high temperature – reels may
soften or warp, and tape peel force may increase. KEMET
recommends that maximum storage temperature not exceed
40˚ C, and maximum storage humidity not exceed 70% rela-
tive humidity. In addition, temperature fluctuations should be
minimized to avoid condensation on the parts, and atmos-
pheres should be free of chlorine and sulfur bearing com-
pounds. For optimized solderability, chip stock should be
used promptly, preferably within 1.5 years of receipt.
