High CV, Long-Lifetime Wet Tantalum Capacitors Designed for Use at 200°C

AVX Corporation has introduced a new series of wet tantalum capacitors designed for use at 200°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 - T4, the new TWA-Y Series delivers high reliability, high temperature, and long lifetime performance, and exhibits stable electrical parameters over temperature (-55°C to +200°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 ideal for use in high temperature avionics, industrial, down-hole, and military applications.

Manufactured in accordance with CECC 30 202-01 (EN 130202), the TWA-Y Series is currently rated for capacitance values spanning 150 to 1,000µF with a ±10% or ±20% capacitance tolerance, voltages spanning 50 - 125V, and temperatures spanning -55°C to +200°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 14 weeks.
