MALVERN, Pa. — Oct. 2, 2017 — To meet the needs of military and avionics applications, Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new high energy wet tantalum capacitor that delivers the industry’s highest capacitance per voltage rating and case size for this device type. For increased design flexibility, the EP1 is available with radial through-hole or surface-mount terminations in the A, B, and C case codes, each with a stud mount option.

Built on Vishay’s proven SuperTan® technology, the device released today features an ultra high capacitance range from 2,000 µF to 30,000 µF in the A case and voltage ratings from 25 VDC to 125 VDC. The EP1’s industry-leading values include a capacitance of 13,000 µF at 50 V in the A case size, which is 18 % greater than the closest competing device. The capacitor features a standard capacitance tolerance of ± 20 %, with ± 10 % tolerance available. C case ratings are expected in late 2017, with B case ratings expected in 2018.

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 0.030 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 A case are available now, with lead times of 10 weeks for larger orders.
