Wet electrolytic tantalum capacitors operate to 200°C

March 14, 2016 // By Julien Happich
AVX Corporation has extended its TWA-Y Series wet electrolytic tantalum capacitors with the addition of high CV 470µF/100V and 1,000µF/75V components rated for operation at temperatures spanning 125°C to 200°C.

TWA-Y Series wet tantalum capacitors are designed for continuous operation at 200°C (with applicable derating) and provide endurance ratings up to 2,000 hours. Featuring a unique cathode system that enables high CV performance in standard DSCC case sizes spanning T1–T4, TWA-Y Series capacitors deliver high reliability, high temperature, and long lifetime performance, and exhibit stable electrical parameters over temperature (-55°C to +200°C).

Hermetically sealed in a welded tantalum can and header assembly, TWA-Y Series capacitors also satisfy the harsh mechanical shock and high frequency vibration requirements for MIL-STD-202 method 204, test condition “D” and method 213, test condition “I,” making them ideal for input and output filtering and energy storage and discharge in high temperature avionics, industrial, and down-hole applications.

The TWA-Y Series is currently rated for capacitance values spanning 68–1,000µF with a ±10% or ±20% capacitance tolerance, rated voltages spanning 50–125V, and temperatures spanning -55°C to +200°C. However, several additional components that will eventually extend the series from 10–1,000µF and 25–125V 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 8–10 weeks.
