Max Cap Capacitor Series

Featuring capacitance values spanning 25mF to 50mF, exceptional electrical & mechanical stability, & extended lifetimes of up to 10,000 hours, the new TWD HTMC series is ideally suited for avionics, defense, & industrial applications that require high capacitance at higher temperatures & for longer lifetimes than EDLC supercapacitor technologies can deliver

AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has released a new series of axial leaded, hermetically sealed wet electrolytic tantalum capacitors that achieve supercapacitor CV values in high temperature environments up to 125°C. Utilizing high CV tantalum powders and a well-established wet tantalum design, TWD High Temp Max Cap (HTMC) Series capacitors deliver exceptional electrical and mechanical stability, achieving extended operational lifetimes of up to 10,000 hours at 85°C, rated voltage. Combined with extremely high capacitance values spanning 25mF to 50mF and a wide operating temperature range spanning -55°C to +125°C, the extended endurance of the new TWD HTMC Series capacitors makes them ideal 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 EDLC (electric double-layer capacitor) supercapacitor technologies can currently deliver.

“The high CV tantalum powders used to develop our new TWD HTMC Series allow us to achieve extremely high capacitance values well within the supercapacitor range, and the hermetic packaging provides high mechanical stability that enables their use in a variety of high temperature, high reliability, and long life applications,” said Chris Reynolds, technical marketing manager, AVX.

Packaged in T4 axial leaded cases, TWD HTMC Series capacitors are currently available rated for 50mF, 6.3V and 25mF, 10V, -55°C to +125°C, and 10,000 hours at 85°C and rated voltage. Additionally, a third rating of 150mF, 2.5V, -55°C to +125°C, and 2,000 hours at 85°C and rated voltage is in active development. TWD HTMC Series capacitors are available with a ±10% and ±20% capacitance tolerance, with and without an insulating sleeve, and with either Sn/Pb (60/40) plated or pure matte tin terminations. The series is also lead-free reflow compatible and RoHS compliant, and is suitable for automatic mounting and soldering. Lead time for the series is 14 weeks.
