The HE4 achieves low ESR thanks to industry-leading anode designs in combination with Vishay’s proven SuperTan hybrid cathode technology. The new capacitor is housed in an all-tantalum, hermetically sealed case featuring a double seal for increased reliability. HE4 is optimised for energy-storage and pulse-power applications.
This new wet tantalum high-energy capacitor combines a robust design with an ultra-high capacitance range from 1100 µF to 72000 µF. This is the highest capacitance per unit volume of any wet tantalum capacitor.
HE4 operates over a temperature range of -55 °C to +85 °C (to +125 °C with voltage derating) and is available in the A, B, and C case codes. Vishay’s new wet tantalum capacitor features a ± 20 % standard capacitance tolerance at 120 Hz and +25 °C, with tolerances of ± 10 % also available.
Samples and production quantities of the new HE4 wet tantalum high-energy capacitor are available now, with lead times of 10 weeks for larger orders.
