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:
1,000Failure rate is usually expressed in terms of percent per
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.
