AVX Corporation has introduced a new series of high CV wet tantalum capacitors that approach the ultra high volumetric capacitance densities of aqueous supercapacitors, as well as surmount their temperature and soldering limitations. Developed using a novel design process based on high CV tantalum powders, the new TWD DCUltraMax™ Series High CV Wet Tantalum Capacitors achieve extremely high DC capacitance values and, unlike aqueous supercapacitors, are rated for continuous high temperature operation to at least 85°C and are compatible with both wave and reflow soldering to a PCB. Currently available with a CV value of 50mF at 6.3V, TWD DCUltraMax Series capacitors are ideal for use in a variety of harsh environment applications, including: pulse applications, energy harvesting, energy storage, military electronics, and avionics.
