Wet tantalum capacitor targets mil/aero applications
To meet the needs of military and avionics applications, Vishay Intertechnology has introduced a high-energy wet tantalum capacitor that delivers what is claimed to be the industry's highest capacitance per voltage rating and case size for this device type. For increased design flexibility, the EP1 is available with radial through-hole or surface-mount terminations in the A, B, and C case codes, each with a stud mount option.
Built on Vishay's proven SuperTan technology, the device features an ultra-high capacitance range from 2,000µF to 30,000µF in the A case and voltage ratings from 25VDC to 125VDC.
The EP1's values include a capacitance of 13,000µF at 50V in the A case size, which is 18 % greater than the closest competing device.
The capacitor features a standard capacitance tolerance of ± 20 %, with ± 10 % tolerance available.
C case ratings are expected in late 2017, with B case ratings expected in 2018.
Optimised 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, and provides maximum ESR down to 0.030Ω at 1kHz and +25°C. The capacitor is available with tin/lead (Sn/Pb) and RoHS-compliant 100% tin terminations.
