NPFC - MIL-PRF-39006
CAPACITORS, FIXED, ELECTROLYTIC (NONSOLID ELECTROLYTE), TANTALUM, ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR
|Publication Date:||15 January 1998|
This specification covers tantalum, electrolytic (nonsolid electrolyte), fixed capacitors (polarized and nonpolarized), hermetically (see 6.7) and nonhermetically sealed in metal cases (see 6.1). Capacitors covered by this specification have reliability established for failure rate levels (FRL) ranging from 2.0 (or 1.0) percent to 0.001 percent per 1,000 hours in accordance with MIL-STD-690. These FRL are established at a 60-percent confidence level and are maintained at a 10-percent producer's risk. A Part Per Million (ppm) quality system is used for assessing the average outgoing quality of ER capacitors supplied to this specification. Statistical Process Control (SPC) techniques are required in the manufacturing process to minimize variation in production of ER capacitors supplied to the requirements of this specification.
This appendix details the procedure for submission of samples, with related data, for qualification inspection of capacitors covered by this specification. This appendix is a mandatory part of the specification. The information contained herein is intended for compliance.

These capacitors covered by this specification are military unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions including: −55°C to +125°C operating temperature range, 54 Gs rms of vibration, up to 500 Gs of shock, 48 hours of salt spray, 1,000 cycles of surge voltage, up to 300 cycles of thermal shock. This specification also has a military unique established reliability failure rate system. In addition these military requirements are verified under a qualification system. Commercial components are not designed to withstand these military environmental conditions.View Less
