Vishay’s T97 Solid Tantalum Chip Capacitors Offer High-Reliability Screening and Surge Current Testing Options With Ultra-Low ESR Values From 0.015 Ω to 0.17 Ω in a Wide Variety of Case Sizes

Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of new TANTAMOUNT® Hi-Rel COTS T97 series solid tantalum chip capacitors, designed to provide high-reliability screening and surge current testing options with extremely low ESR performance.

Featuring dual anode construction to ensure the lowest ESR in their class, the new T97 capacitors are designed for safety-critical applications such as those found in the military, aerospace, and medical industries. Typical end products include weapons and radar systems, avionics, space-based electronics, and medical instrumentation. The new devices offer designers a wide array of ratings not found in available MIL specifications, combining the flexibility and convenience of a commercial product with the reliability needed in demanding applications.

These conformal-coated capacitors offer high-reliability screening options including Weibull grading, and surge current testing options in accordance with MIL-PRF-55365 in a wide variety of case sizes. This differentiates these capacitors from commercial grade capacitors by featuring the required reliability and surge screening options necessary to ensure performance in Hi-Rel applications while still maintaining a maximum capacitance-voltage product, a figure of merit that measures the amount of energy a capacitor can store, and helps designers choose the best capacitor for their applications.

The devices released today, part of Vishay’s TANTAMOUNT tantalum capacitor family, have a capacitance range of 22 µF to 1500 µF and a voltage range from 4 V to 50 V. They offer ultra-low ESR values, which range from 0.015 Ω to 0.17 Ω at +25 °C and 100 kHz. Devices in the T97 series operate over a temperature range of –55 °C to +125 °C.

Their extended capacitance and voltage values – coupled with reliability, surge current, and ESR options – make the T97 tantalum capacitors a flexible solution in demanding applications where the cost of failure is high. The T97 will additionally reduce costs and time to market by eliminating the need for customer drawings, source control drawings, or special part numbers.

The surface-mount T97 capacitors are available in standard EIA tape-and-reel packages and feature standard SnPb terminations, with 100 % tin terminations available.

Samples and production quantities of the new T97 solid tantalum chip capacitors are available now, with lead times of 8 to 10 weeks for larger orders.
