Wet electrolytic tantalum capacitor for defence, aerospace and industrial use

AVX Corporation offers a high-temperature wet electrolytic tantalum capacitor series. Intended for employment at 230C, the new TWA-X Series wet electrolytic tantalum capacitors offers a high-capacitance cathode system that delivers high CV performance in standard case sizes and a hermetically sealed, welded tantalum can and header assembly that gives robust resistance against mechanical shock and high-frequency vibration.

Ideal for application in defence, aerospace, industrial, and oil drilling equipment, the capacitors are also mechanically tested in accordance with MIL-STD-202 and give the highest capacitance for the longest duration – up to 400μF for 500 hours of operation at 230C in the form factors offered. They are currently offered in DSCC case size T4 (AVX case size 'E') with two initial ratings of 400μF/100V and 330μF/125V.

“Our TWA-X Series offers high-temperature versions of conventional wet electrolytic tantalum capacitors and is especially well suited for use in oil drilling and other high-temperature, harsh environment applications,” said Mitch Weaver, a member of the technical staff at AVX.
