Vishay Intertechnology Extends EP1 High Energy Wet Tantalum Capacitor With New Ratings in the B and C Case Codes

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

MALVERN, Pa. — Sept. 21, 2020 — 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. Pricing for U.S. delivery starts at $825 per piece for minimum order quantity.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
