Abstract : Production engineering measures for improving production techniques to increase the reliability of high voltage, high temperature aluminum electrolytic capacitors have been completed. The required number of capacitors for each contract item were life tested at 85C for 10000 hours. There were 9400 capacitors on the extended life test. Reliability for CU13 and CU17 capacitors and contract item 2AG rated 1.5 mfd - 400 V are shown. The verification testing, which was performed at 125 C on 40 capacitors for each contract item, met the requirements of MIL-C-39018A. It further demonstrated that in addition to CU13 styles which are designed to operate at 125 C, the CU17 manufactured for this contract are capable of operating at 125C with derated voltage. Process specifications and Quality Control Manual are included.
