KYOCERA AVX extends TWA-Y Series of wet tantalum capacitors

KYOCERA AVX has expanded its TWA-Y Series high-temperature, COTS-Plus wet electrolytic tantalum capacitors to include the new 470µF  capacitor which exhibits the world’s highest CV/cc at 200°C and 125V, reliably withstands continuous operation at 200°C for up to 2,000 hours with applicable derating. It also features a leaded, cylindrical, and hermetically sealed construction field-proven to ruggedly withstand shock and vibration and is an ideal drop-in replacement for existing M39006-style wet tantalum capacitors used for input and output filtering and energy storage and discharge in high-temperature industrial and downhole oil-drilling applications.

Unlike conventional wet electrolytic tantalum capacitors, KYOCERA AVX’s TWA-Y Series capacitors employ a unique cathode system.

Featuring a hermetically sealed, welded tantalum can and header assembly and an optional insulation sleeve, TWA-Y Series capacitors ruggedly withstand harsh mechanical shock and high-frequency vibration per MIL-PRF-39006 and MIL-STD-202 (method 204, test condition “D” and method 213, test condition “I”) and exhibit stable electrical parameters over the full range of operating temperatures, extending from -55°C to +200°C.

TWA-Y Series high-temperature, COTS-Plus wet electrolytic tantalum capacitors are currently available in four case sizes (DLA T1–T4) with capacitance values extending from 10–4,700µF (±10% or ±20% tolerance) and rated voltages spanning 15–125V
