APPLICATION INFORMATION
Capacitors may be operated at less than the rated voltage,
resulting in significantly reduced leakage current values.
In timing circuits, or other applications where the device is
subjected only to a DC voltage, the ballistic or DC
capacitance will be somewhat larger than measured at 50 Hz.
The parametric information must necessarily be brief,
although additional comprehensive data is available on
request, and the tests tailored to customers’ requirements
can be made.
RELIABILITY
All capacitors are subjected to burn-in. This is to remove
infant mortalities and ensure reliability. The capacitor lifetime
is enhanced when the unit is subjected to a reduced ripple
current, a low ambient temperature, and is externally cooled.
The use of a heat sink is recommended.
STACKING
The units are suitable for stacking by use of through bolts. It
is strongly recommended that a metal heat sink is used
between each unit in order to eliminate the possibility of hot
spots.

ESTABLISHED FAILURE RATE
The MT range incorporates 735D capacitors which are
structurally similar to and subjected to the same processes
as our 135D and MIL-PRF-39006 range which is to an
established failure rate of level R, 0.01 % per 1000 h at a
60 % confidence level. The CECC system of testing does not
readily yield data to prove these levels, but in-house testing
supports this figure.
Although failure rates derived from life tests are a useful
guide, in practice capacitors rarely see conditions of a steady
DC voltage and temperature. The construction of the MT
module gives an ability to handle the high ripple currents at
high frequencies, reverse voltages up to 3 V, and extremes
of temperature likely to be encountered in modern circuitry.
ALTERNATIVE CONSTRUCTION
Alternative constructions based on the module range with
differing terminal configurations and capacitor combinations
including series connected units are available.
