Vishay’s New Wet Tantalum Capacitor Offers Industry’s Highest Capacitance Value

Vishay Intertechnology, Inc. (NYSE: VSH) in April announced a new ultra-high capacitance, wet tantalum capacitor approved to the new DSCC Drawing 10004. Vishay’s new DSCC 10004 device features the industry’s highest capacitance in the axial T1, T2, T3, and T4 case codes. For high reliability applications, the extended SuperTan® 10004 features a glass-to-metal hermetic seal, operates over a temperature range of – 55 °C to + 85 °C, to + 125 °C with voltage derating, and provides low maximum ESR down to 0.25 Ù at + 120 Hz. With a unique cathode system that provides the highest capacitance per unit volume available, the 10004 represents a major breakthrough in wet tantalum capacitor technology. The device combines the inherent reliability of wet tantalum with the capacitance stability of solid tantalum to eliminate circuit impedance restrictions and dramatically increase capacitance ratings With a rugged, all-tantalum construction manufactured to withstand high stress and hazardous environments; the new capacitor provides reliable performance in low-voltage filtering and energy storage applications for demanding, high-stress military and aerospace systems including weapon systems, radars, transponders, and power supplies. The device offers capacitances from 180 μF to 10,000 μF, and capacitance tolerances of ± 20 % standard at 120 Hz and + 25 °C, with tolerances of ± 10 % available. By providing designers with a new high standard for capacitance in a single device, the new capacitor enables reduction of capacitor or component count, lowers the amount of board space required, and simplifies the overall manufacturing and assembly process. The device features standard tin/lead terminations. Samples and production quantities of the new 10004 wet tantalum capacitor are available now, with lead times of 8 weeks for larger orders.
