Vishay Sprague extends Hi-Rel COTS T97 series to offer the industry's first solid tantalum chip capacitor with 63-V rating and 22-µF capacitance to meet derating requirements in +28-V power supply designs. Designed for safety-critical applications such as those found in the military and aerospace industries, the new T97 Hi-Rel series features the required reliability and surge screening options necessary to ensure performance in Hi-Rel applications while still maintaining a maximum capacitance-voltage product. The ratings are also available in a commercial version, the 597D series.
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 TANTAMOUNT® Hi-Rel COTS 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.
