FOUNTAIN INN, S.C. – AVX Corporation announced that several of its TWA Series axial-leaded, hermetically sealed wet electrolytic tantalum capacitors are now qualified to MIL-PRF-39006/33A. Designed to deliver high-reliability, high-CV performance in harsh-environment military, defense, avionics, and industrial applications, including satellites, DC/DC power supplies, power converters, bulk energy storage, and pule power circuits, the new TWA M39006 Series capacitors have a cylindrical, axial-leaded case with a hermetically sealed welded tantalum can and header assembly that ruggedly withstands environmental hazards including shock, vibration, and temperatures extending from -55°C to +125°C, and a unique cathode system that provides impressively high CV/cc and stable electrical parameters.
TWA Series capacitors currently on the MIL-PRF-39006 qualified parts list (QPL) are manufactured at the AVX facility in Lanškroun, Czech Republic, and include T3 and T4 case sizes with M-level reliability (i.e., failure rates of 1% per 1,000 hours), capacitance values spanning 470–1800µF, and voltage ratings ranging from 25–75V. The TWA M39006 Series capacitors also exhibit low DC leakage (5–12µA at +25°C and 20–50µA at +85°C and +125°C) and low ESR (0.5–0.9Ω max. at 120Hz).
Parts with P-level reliability (i.e., failure rates of 0.1% per 1,000 hours) are currently in the midst of the qualification process, and additional capacitance values, voltage ratings, and case sizes will follow. Lead-time for the series is currently 10–14 weeks.
