Vishay Releases New HE3 Wet Tantalum High-Energy Capacitor with Ultra-High Capacitance Range of 3300 MF to 72000 MF

Device Utilizes SuperTan® Technology to Provide Low ESR of 0.035 O

Selb, (PresseBox) - Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of a new wet tantalum high-energy capacitor that offers the highest capacitance of any similar device on the market. The HE3 features a unique case design with SuperTan® technology for improved reliability and performance in high-energy applications.

Optimized for energy-storage and pulse-power applications in high-reliability avionics and military devices, Vishay’s HE3 is housed in an all tantalum, hermetically sealed case, and is manufactured to withstand high stress and hazardous environments.

The design features a unique double seal for improved reliability and performance, while providing a capacitance range of 3300mF to 72000mF, the highest capacitance per unit volume of any wet tantalum capacitor.

The HE3 represents a major breakthrough in wet tantalum capacitor technology by utilizing Vishay’s proven SuperTan hybrid cathode technology in combination with industry-leading anode designs. Its ESR is a very low 0.035 O at +25°C and 1kHz.

The new capacitor operates over a temperature range of –55°C to + 85°C. It offers a ±20% standard capacitance tolerance at 120Hz and +25°C, with tolerances of ±10% also available.

Samples and production quantities of the new HE3 wet tantalum high-energy capacitor will be available in June 2007, with lead times of approximately 8 to 10 weeks for larger orders.
