High-energy capacitor

  • 15-Aug-2013 12:45 EDT

Vishay Intertechnology’s HE4 wet tantalum high-energy capacitor for military and aerospace applications is built on SuperTan hybrid cathode technology. The device offers low ESR down to 0.025 Ω at +25°C and 1 kHz as well as capacitance from 1100 μF to 72000 μF. Optimized for energy-storage and pulse-power applications, the device is housed in an all-tantalum, hermetically sealed case featuring a double seal for increased reliability. Offered in the A, B, and C case codes, the HE4 operates over a temperature range of -55 to +85°C (to +125°C with voltage derating) and features a ±20% standard capacitance tolerance at 120 Hz and +25°C, with tolerances of ±10% also available.
