Robust tantalum capacitor suits defence and avionics

It is in stock at distributor New Yorker Electronics.

The new Vishay EP2 Wet Tantalum Capacitor offers industry-high capacitance, mechanical robustness for military and avionics systems.

Available with radial through-hole terminations with a stud mount option in the B and C case codes, the capacitors can be used as an exact drop-in replacement for competing parts or as a higher capacitance alternative in a mechanically equivalent package to reduce component counts, save space and lower design costs.

Built on Vishay’s SuperTan technology, the device features ultra-high capacitance from 2,700µF to 48,000µF in the B case code and 3,600µF to 72,000µF in the C case code. Voltage ratings for the capacitor range from 25VDC to 125VDC.

The EP2’s industry-leading values include a capacitance of 9,000µF at 80V and 58,000µF at 35V in the C case size.

These values are 50% and 21% greater, respectively, than the closest competing device. The capacitor features a standard capacitance tolerance of ± 20%, with ± 10% tolerance available.

Optimised for pulse power and energy hold-up applications in laser guidance, radar, and avionics systems, the EP2 is housed in an all-tantalum, hermetically sealed case for increased reliability. Offering robust mechanical performance, the capacitor features high vibration (high frequency: 20g; random: 19.64g) and mechanical shock (50g) capabilities.

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 0.017Ω at 1kHz and +25°C.

The capacitor is available with tin / lead (Sn / Pb) and RoHS-compliant 100% tin terminations.

Applications cover industrial, avionics/military/space and capacitor banks.

Samples and production quantities of the EP2 are available now through New Yorker Electronics with lead times of 16 weeks for larger orders.
