Vishay has extended its EP1 range of wet-tantalum capacitor, supplying the industry’s highest capacitance per voltage-rating for this device type, according to New Yorker Electronics, which is stocking them. “Vishay developed this upgraded capacitor to meet the needs of military and avionics applications with new ratings in the B and C case codes.”

The parts are optimised for pulse power and energy hold-up applications in laser guidance, radar, avionics and space systems.

They are housed in an all-tantalum hermetically-sealed case for increased reliability and are available with radial through-hole or surface-mount terminations in the A, B, and C case codes, each with a stud-mount option. Termination options are Sn-Pb or RoHS-compliant 100% tin.

Values are:

• 3,600µF to 40,000µF in B cases (35.6 x 35.6 x 11.4mm)
• 5,300µF to 58,000µF in C cases (35.6 x 35.6 x 15.1mm)

Devices are available at ratings are between 25 and 125Vdc.

The ‘industry’s highest capacitance per voltage’ claim is based on a 12,000µF 80V capacitor in a C case.

Standard tolerance is ±20%, with ±10% an option.

Operation is over -55°C to +85°C, and up to +125°C with voltage derating.

Maximum ESR can be as low as 15mΩ at 1kHz +25°C.
