Vishay wet tantalum capacitor optimised for avionics systems

New Yorker Electronics has released the Vishay EP1 Wet-Tantalum capacitor, said to supply the industry’s highest capacitance per voltage-rating for this device type.

This upgraded capacitor has been developed to meet the needs of military and avionics applications with new ratings in the B and C case codes.

Optimised for pulse power and energy hold-up applications in laser guidance, radar, and avionics/space systems, the EP1 is housed in an all-tantalum, hermetically sealed case for increased reliability. Vishay’s EP1 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 3,600µF to 40,000µF in the B case code and 5,300µF to 58,000µF in the C case code. Voltage ratings for the device range from 25VDC to 125VDC. The EP1’s values include a capacitance of 12,000µF at 80V 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.

Featuring standard tolerance of ±20%, with ±10% available, the device operates over a temperature range of -55°C to +85°C, to +125°C with voltage derating. The Vishay wet Tantalum Capacitor provides maximum ESR down to 0.015Ω at 1kHz and +25°C. It is available with tin / lead (Sn/Pb) and RoHS-compliant 100% tin terminations.
