Military Style Capacitors
Military style capacitors are manufactured by Dearborn Electronics, Inc. to meet all the requirements
of the pertinent military specifications. All capacitors ordered by the military part number will be man-
ufactured, tested and marked in accordance with the military specifications. The military specification
shall be used for verification for specific operational parameters and other characteristics.
Copies of the Mil Specs are available @ www.dscc.dla.mil/Programs/MilSpec/DocSearch.asp
Established Reliability Capacitors
The reliability of these capacitors is established by continuous life testing performed at maximum
rated voltage and maximum rated temperature. The maximum failure rate at 90% confidence level is
expressed as percent failures for each 1000 hours of test. Dearborn has attained a failure rate level of
0.001% per 1000 hrs on certain of these specifications. This is the lowest failure rate available for
these specificstions and the true failure rates are much lower than stated. The failure rate levels
attained for each specification are listed on the following page. Failure rate levels are 1%/1000 hrs (M),
0.1%/1000 hrs (P), 0.01%/1000 hrs (R), and 0.001%/1000 hrs (S).
