200°C High-CV, Long-Lifetime Wet Tantalum Capacitors

AVX Corporation has introduced a new series of wet tantalum capacitors designed for use at 200 degrees C, many of which are capable of up to 2,000 hours of operation with applicable derating. Featuring a high capacitance cathode system that enables high CV performance in standard DSCC case sizes spanning T1 to T4, the new TWA-Y Series delivers high-reliability, high-temperature, and long-lifetime performance, and exhibits stable electrical parameters over temperature (-55 to +200 degrees C).

Hermetically sealed in a welded tantalum can and header assembly, TWA-Y Series capacitors satisfy the harsh mechanical shock and high frequency vibration requirements for both MIL-PRF-39006 and MIL-STD-202, making them suited for use in high temperature avionics, industrial, down-hole, and military applications.

“Exhibiting high reliability and high capacitance performance at 200°C, with endurance ratings up to 2,000 hours, the new TWA-Y Series hermetically sealed wet electrolytic tantalum capacitors provide design engineers with an extended range of temperatures and CV values, enabling a range of new, next-generation electronics for harsh environment applications,” said Allen Mayar, product marketing manager at AVX.

Manufactured in accordance with CECC 30 202-01 (EN 130202), the TWA-Y Series is currently rated for capacitance values spanning 150- to 1,000-µF with a ±10% or ±20% capacitance tolerance, voltages spanning 50V to 125V, and temperatures spanning -55 to +200 degrees C; however, several additional capacitance and voltage ratings are in active development. Supplied with either SnPb 60/40 or lead free compatible and RoHS compliant matte tin terminations in a tray pack, lead time for the series is 10 to 14 weeks.
