IoT Computers Components Computers Electro Optic & Camera Packaging & Production Motion Automotive New Products AVX Corporation, a leading manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, has launched a new high- temperature wet electrolytic tantalum capacitor series. Designed for use at 230°C, the new TWA-X Series wet electrolytic tantalum capacitors feature a high-capacitance cathode system that achieves high CV performance in standard case sizes and a hermetically sealed, welded tantalum can and header assembly that provides robust resistance against mechanical shock and high-frequency vibration. Ideal for use in military, aerospace, industrial, and oil drilling equipment, TWA-X Series capacitors are also mechanically tested in accordance with MIL-STD-202 and provide the highest capacitance available for the longest duration — up to 400μF for 500 hours of operation at 230°C — of any wet tantalum capacitor in the form factors offered. They are currently available in DSCC case size T4 (AVX case size “E”) with two initial ratings: 400μF/100V and 330μF/125V. “Our new TWA-X Series offers high-temperature versions of conventional wet electrolytic tantalum capacitors and is especially well suited for use in oil drilling and other high- temperature, harsh environment applications,” said Mitch Weaver, a member of the technical staff at AVX. The axial-leaded T4 (“E”) case TWA-X Series capacitors measure 26.97mm in length and either 10.31mm in diameter with an insulating sleeve or 9.52mm in diameter without an insulating sleeve. The axial leads are available in RoHS- compliant, lead-free compatible matte tin or in 60/40 tin/lead and measure 57.15mm in length. The 400μF/100V TWA-X Series capacitors are rated for 2,000 hours at 200°C when derated to 60V and for 500 hours at 230°C when derated to 25V. The 330μF/125V parts are rated for 500 hours at 200°C when derated to 75V and for 500 hours at 230°C when derated to 40V.

The demonstration was also supported by the CPER “Photonics for society” and contributes to the “digital world” Hub 3 of the I-Site Université de Lille Nord de France. “Tektronix is delighted to be working in such close collaboration with IEMN on achieving this prestigious breakthrough,” said Dr. Klaus Engenhardt, CTO Tektronix EMEA. “It’s exciting to see our industry- leading end-to-end transmit and receive solution used to help bridge coherent optical and THz transceiver technologies. Advanced test tools are needed today to generate and characterize signals at 100G, 400G and beyond and Tektronix offers a wide portfolio of optical communication test solutions.” The Tektronix test equipment used in the IEMN demonstration included an AWG70000 Series 50GS/s arbitrary waveform generator, DPO70000SX 70GHz oscilloscopes and an OM5110 46GBd coherent optical transmitter. Tektronix has a long history of collaboration with IEMN on THz communications research and most recently supported the first data transmission through a THz multiplexer.
