Offering the industry’s highest capacitance per voltage rating and case size for this device type, the capacitor is now 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 features ultra-high capacitance from 3,600 to 40,000 µF in the B case code and 5,300 to 58,000 µF in the C case code. Voltage ratings for the device range from 25 to 125 VDC.
The EP1’s top 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 capacitor also 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 EP1 is housed in an all-tantalum, hermetically sealed case for increased reliability. The device operates over a temperature range of -55° C to +85° C, to +125° C with voltage derating. It also provides maximum ESR down to 0.015 Ω at 1 kHz and +25° C. The capacitor is available with tin / lead (Sn / Pb) and RoHS-compliant 100 % tin terminations.
Samples and production quantities of the EP1 B and C case are available now, with lead times of 16 weeks for larger orders.
