Vishay Intertechnology has extended its EP1 wet tantalum capacitor to meet the requirements of military and avionics applications. The new device delivers the industry’s highest capacitance of 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 with an average voltage rating ranging from 25 VDC to 125 VDC.
The new capacitor has been designed based on the Vishay’s SuperTan technology and they offer 33% greater capacitance than the other competing devices, with a standard capacitance tolerance of ± 20%. The device is available in radial through-hole or surface-mount terminations in the A, B, and C case codes, hence they can be used in pulse power and energy hold-up applications in laser guidance, radar, and avionics systems.
The new capacitor is available with tin/lead (Sn/Pb) and RoHS-compliant 100% tin terminations and operates at a temperature range of -55 °C to +85 °C, to +125 °C with voltage derating, and provides maximum ESR down to 0.015 Ω at 1 kHz and +25 °C.
