Offering Industry-High Capacitance, Device Features Multiple Termination and Mounting Options for Design Flexibility in Military and Avionics Systems

To meet the needs of military and avionics applications, Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its EP1 wet tantalum capacitor with new ratings in the B and C case codes. Offering the industry’s highest capacitance per Voltage rating and case size for this device type, the capacitor is available with radial through-hole or surface-mount terminations in the A, B, and C case codes, each with a stud-mount option, for increased design flexibility.

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. Voltage ratings for the device range from 25 VDC to 125 VDC. The EP1’s industry-leading Values include a capacitance of 12,000 µF at 80 V in the C case size, which is 33 % greater than the closest competing device. The capacitor features a standard capacitance tolerance of ± 20 %, with ± 10 % tolerance available.

Optimized for pulse power and energy hold-up applications in laser guidance, radar, and avionics systems, the EP1 is housed in an all-tantalum, hermetically sealed case for increased reliability. 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 capacitor is available with tin / lead (Sn / Pb) and RoHS-compliant 100 % tin terminations.

Samples and production quantities of the EP1 B and C case are available now, with lead times of 16 weeks for larger orders.
