AVX has extended its TWA-Y Series wet electrolytic tantalum capacitors with the addition of new, high CV 470µF/100V and 1,000µF/75V components. These components act as drop-in replacements for existing M39006-style wet tantalum capacitors in applications that may require 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 and method 213, test condition, making them ideal for input and output filtering and energy storage and discharge in high temperature avionics, industrial, and down-hole applications.
The still-expanding 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.
