To meet the needs of military and avionics applications, Vishay Intertechnology introduced a Wet Tantalum Capacitor that delivers the industry’s highest capacitance per voltage rating and case size for this device type. The Vishay EP2 Wet Tantalum Capacitor offers industry-high capacitance and mechanical robustness for military and avionics systems.

Available with radial through-hole terminations, with a stud mount option in the B and C case codes, the Vishay EP2 Series 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 2,700µF to 48,000µF in the B case code and 3,600µF to 72,000µF in the C case code. Voltage ratings for the capacitor range from 25VDC to 125VDC. The EP2’s industry-leading values include a capacitance of 9,000µF at 80V and 58,000µF at 35V in the C case size. These values are 50% and 21% greater, respectively, 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 EP2 is housed in an all tantalum, hermetically sealed case for increased reliability. Offering robust mechanical performance, the capacitor features high vibration (high frequency: 20g; random: 19.64g) and mechanical shock (50g) 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 0.017Ω at 1kHz and +25°C. The capacitor is available with tin / lead (Sn / Pb) and RoHS-compliant 100% tin terminations.
