| Dramatic increase in capacitance range | |||
Vishay Intertechnology's STE products dramatically increase attainable capacitance ratings for wet tantalum capacitors. Due to its rugged, all-tantalum construction, the STE (SuperTan® Extended) Series is especially suited to filtering and energy storage applications in demanding, high-stress military and aerospace applications including weapon systems, radars, transponders and power supplies. The devices employ a unique cathode system to provide industry-leading specifications in terms of capacitance per unit volume. The hermetically sealed, extended-range STE devices are available in industry-standard T1, T2, T3 and T4 case sizes. In the T4 case size, measuring 1.062inch (26.97mm) long and 0.375inch (9.53 mm) in diameter, the new series offers capacitance ratings of 750µF at 75V and 6000µF at 16V, ratings that are up to six times greater than those of conventional wet tantalum products.  By providing designers with a new standard for capacitance in a single device, Vishay’s STE capacitors enable reduction of capacitor or component count, reduce the amount of board space required and simplify the overall manufacturing and assembly process. STE capacitors can withstand a 2,000-hour life test at a temperature of +85°C at the applicable rated DC working voltage. Capacitance tolerance at 120Hz and +25°C is ±20%; ±10% is available upon request. The devices' operating temperature range is -55°C to +85°C. This may be extended to +125°C with proper de-rating.
