Vishay’s newly extended EP1 wet-tantalum capacitor, supplying the industry’s highest capacitance per voltage-rating for this device type, is now available from New Yorker Electronics. Vishay developed this upgraded capacitor to meet the needs of military and avionics applications with new ratings in the B and C case codes.
Optimized for pulse power and energy hold-up applications in laser guidance, radar and avionics/space systems, the Vishay EP1 is housed in an all-tantalum, hermetically sealed case for increased reliability. The 
Source: New Yorker Electronicscapacitor 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 V DC to 125 V DC. 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 device features a standard capacitance tolerance of ±20%, with ±10% tolerance available, and operates over a temperature range of -55° C to 85° C, to +125° C with voltage derating. The Vishay wet tantalum capacitor provides maximum equivalent series resistance down to 0.015 Ω at 1 kHz and 25° C and is available with either tin/lead and RoHS-compliant 100% tin terminations.
