New Yorker Electronics has released Vishay’s newly extended EP1 Wet-Tantalum Capacitor, providing the industry’s highest capacitance per voltage-rating for this device type. The company developed this upgraded capacitor to satisfy the needs of defence and avionics applications with new ratings in the B and C case codes.


Optimised for pulse power and energy hold-up applications in radar, laser guidance, and avionics/space systems, the device is accommodated in an all-tantalum, hermetically-sealed case for boosted reliability. The capacitor is offered with radial through-hole or surface-mount terminations in the A, B, and C case codes, each with a stud-mount option, for enhanced design flexibility.


Built on the company’s SuperTan technology, the device now offers 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 device’s industry-leading values comprise a capacitance of 12,000µF at 80V in the C case size, which is 33% better than the nearest competing device. The capacitor offers a standard capacitance tolerance of ±20%, with ±10% tolerance available.


Providing standard tolerance of ±20%, with ±10% available, the device functions over a temperature range of -55C to +85C, to +125C with voltage derating. The capacitor delivers maximum ESR down to 0.015Ohm at 1kHz and +25C. It is offered with tin/lead (Sn/Pb) and RoHS-compliant 100% tin terminations.
