Wet electrolytic tantalum capacitors

24 February 2016 Passive Components

AVX has extended its TWA-Y series wet electrolytic tantalum capacitors with the addition of new, high CV 470 μF/100 V and 1000 μF/75 V 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.

The components are designed for continuous operation at 200°C (with applicable derating) and provide endurance ratings up to 2000 hours. Featuring a unique cathode system that enables high CV performance in standard DSCC case sizes spanning T1-T4, they 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 - 1000 μF with a ±10% or ±20% capacitance tolerance, rated voltages spanning 50 – 125 V, and temperatures spanning -55°C to +200°C. Several additional components that will eventually extend the series from 10 – 1000 F and 25 – 125 V 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.
