One of the Industry's First Solid Tantalum Chip Capacitors to Offer 63-V Rating and 22-µF Capacitance


TANTAMOUNT® Hi-Rel COTS T97 Series Solid Tantalum Chip CapacitorVishay has extended its TANTAMOUNT® Hi-Rel COTS T97 series to offer one of the industry’s first solid tantalum chip capacitors with a 63-V rating to meet derating requirements in +28-V power supply designs.

Lacking alternatives for +28-V applications, until now designers have been forced to rely on 50-V tantalum capacitors, which are unable to meet derating requirements (both military and best-commercial-practices) of 50% of the rated voltage. With a 63-V rating and capacitance of 22 µF, the new T97 device in the "F" case size solves this long-standing issue by allowing designers to incorporate solid surface-mount tantalum capacitors into their +28-V power supply designs while fully complying with derating requirements. In addition to the T97 Hi-Rel series, these ratings are also available in a commercial version, the 597D series.

Featuring a dual anode construction to ensure one of the lowest ESR ratings in its class, the T97 series is 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. The 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 with wrap-around terminations offer high-reliability screening options including Weibull grading, and surge current testing options in accordance with MIL-PRF-55365 in five case sizes. This differentiates T97 devices 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.
