Vishay Releases New HE3 Wet Tantalum High-Energy Capacitor With Ultra-High Capacitance Range of 3300 μF to 72000 μF
Device Utilizes SuperTan? Technology to Provide Low ESR of 0.035 Ω
Vishay Intertechnology, Inc. (NYSE: VSH) 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 3300 μF to 72000 μF, 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 Ω at +25 °C and 1 kHz.
The new capacitor operates over a temperature range of - 55 °C to + 85 °C. It offers a ±20 % standard capacitance tolerance at 120 Hz and + 25 °C, with tolerances of ±10 % also available.
