Vishay claims solid tantalum chip capacitors are first with 75-V rating

Malvern, Pa.—Extending its leading position in high-voltage solid tantalum chip capacitors, Vishay Intertechnology Inc. announced that the company's TANTAMOUNT Hi-Rel COTS T97 and commercial, industrial-grade 597D series have been enhanced with an industry-high 75-V rating.

With a 75-V rating and capacitance of 10 µF in the "R" case size, the T97 and 597D series provide high reliability in circuits with applied voltages between 25 V and 40 V, a performance level that has previously been available only with through-hole technology, according to Vishay.

The conformal-coated capacitors with wrap-around terminations feature a dual anode construction to ensure the lowest ESR in their class. The 597D capacitors are optimized for industrial automation and control systems, and the T97 devices are designed for safety-critical applications, such as those found in the military and aerospace industries, including dc-to-dc converters and power distribution in weapons and radar systems, avionics, and space-based electronics.

Part of Vishay's TANTAMOUNT tantalum capacitor family, the T97 and 597D series feature a capacitance range of 10 µF to 1500 µF and a voltage range from 4 V to 75 V in nine case sizes, including the "V" case with a low 2-mm profile. The devices offer ultra-low ESR values down to 0.015 Ω at + 25 °C and 100 kHz, and high ripple currents to 4.1 A. The capacitors operate over a temperature range of – 55°C to + 85°C, to + 125°C with voltage derating.

Pricing: For U.S. delivery starts at $4.20 per piece.
