Capacitors withstand 200°C operation for 2,000 hours
Designed for use in high temperature avionics, industrial, down-hole and military applications, AVX has introduced a 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. The TWA-Y series delivers high reliability, high temperature and long lifetime performance, exhibiting stable electrical parameters over a temperature range from -55 to +200°C.
Featuring a high capacitance cathode system that enables high CV performance in standard DSCC case sizes spanning T1 – T4, the capacitors are hermetically sealed in a welded tantalum can and header assembly. The TWA-Y series capacitors satisfy the harsh mechanical shock and high frequency vibration requirements for both MIL-PRF-39006 and MIL-STD-202.
Allen Mayar, Product Marketing Manager, AVX, commented: “Exhibiting high reliability and high capacitance performance at 200°C, with endurance ratings up to 2,000 hours, the 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 next-gen electronics for harsh environment applications."
Manufactured in accordance with CECC 30 202-01 (EN 130202), the TWA-Y series is currently rated for capacitance values from 150 to 1,000µF with a ±10 or ±20% capacitance tolerance and voltages of 50-125V. 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.
