Device Can Be Used as an Exact Drop-in Replacement for Competing Solutions or a Higher Capacitance Alternative to Reduce Component Counts and Lower Design Costs

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. Available with radial through-hole terminations with a stud mount option in the B and C case codes, the EP2 can be used as an exact drop-in replacement for competing parts or as a higher capacitance alternative in a mechanically equivalent package to reduce component counts, save space, and lower design costs.

Built on Vishay’s proven SuperTan® technology, the device released today features ultra high capacitance from 2,700 µF to 48,000 µF in the B case code and 3,600 µF to 72,000 µF in the C case code. Voltage ratings for the capacitor range from 25 VDC to 125 VDC. The EP2’s industry-leading values include a capacitance of 9,000 µF at 80 V and 58,000 µF at 35 V in the C case size. These values are 50 % and 21 % greater, respectively, than those of 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 EP2 is housed in an all-tantalum, hermetically sealed case for increased reliability. Offering robust mechanical performance, the capacitor features high vibration (high frequency: 20 g; random: 19.64 g) and mechanical shock (50 g) capabilities.

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 0.017 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 EP2 are available now, with lead times of 16 weeks for larger orders.
