Vishay Intertechnology has released high energy wet tantalum capacitor with new ratings in the B and C case codes thereby expanding its EP1 wet tantalum capacitor series for military and avionics applications. Built on Vishay’s proven SuperTan technology, the enhanced EP1 now features ultra-high capacitance from 3,600 µF to 40,000 µF in the B case code and 5,300 µF to 58,000 µF in the C case code. The voltage ratings for the device range from 25 VDC to 125 VDC.

The EP1 comes in an all-tantalum, hermetically sealed case ensures increased reliability thereby making it perfect for pulse power and energy hold-up applications in laser guidance, radar, and avionics systems. The device operates over a temperature range of -55 °C to +85 °C, to +125 °C with voltage derating, and provides maximum ESR down to 0.015 Ω at 1 kHz and +25 °C.

The capacitance of the EP1 series is 12,000 µF at 80 V in the C case size, which is 33 % greater than the competing device. The capacitor features a standard capacitance tolerance of ± 20 %, with ± 10 % tolerance available. It is available with tin / lead (Sn / Pb) and RoHS-compliant 100 % tin terminations.
