The newly improved HTMC Series provides the highest DC capacitance & the highest operating temperature of any T4-case capacitor on the market, plus exceptional electrical & mechanical stability for extended lifetimes of up to 10,000 hours.

FOUNTAIN INN, S.C. (August 29, 2018) – AVX Corporation, a leading manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, has increased the maximum operating temperature for its TWD High-Temp Max-Cap (HTMC) Series axial leaded, hermetically sealed wet tantalum capacitors from 125°C to 175°C. Based on a well-established wet tantalum design, the newly improved TWD HTMC Series capacitors provide the highest DC capacitance and the highest operating temperature of any T4-case capacitor available on the market. Currently available in two ratings, 50mF/6.3V and 25mF/10V, the series achieves high capacitance values previously only offered by supercapacitors and delivers exceptional electrical and mechanical stability for extended lifetimes of up to 10,000 hours at +105°C and rated voltage and, for the 25mF/10V rating, up to 2,000 hours at +175°C and derated voltage.

Ideal applications for TWD HTMC Series capacitors now extend to high-temperature oil and gas market applications, including down-hole drilling equipment, that require proven high-reliability performance at temperatures in excess of 125°C. The series is also well suited for use in DC hold-up and low frequency pulse circuitry in avionics, defense, specialized industrial, and other high-reliability applications that require high capacitance at higher temperatures and for longer lifetimes than electric double-layer capacitor (EDLC) supercapacitor technologies can currently deliver.

“Made using high-quality tantalum powders and established designs, our field-proven HTMC Series hermetically sealed wet tantalum capacitors deliver exceptional electrical and mechanical performance and long-lifetime durability in a range of high-temperature, high-reliability applications that now extends to the oil and gas industry,” said Mitch Weaver.
