3,600µF to 40,000µF wet tantalum capacitor

Vishay developed this upgraded capacitor 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 industry-leading 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.

The capacitor features a high energy, very high capacitance design in an all tantalum, hermetically sealed case.

Patents are pending. There are two terminations options. These are SMD and radial.

Besides industrial and avionics, military and space applications the device is ideal for capacitor banks

Samples and production quantities of the EP1 B and C case are available now from New Yorker Electronics, with lead times of 16 weeks for larger orders.
