Tantalum Caps Handle Military Apps
Targeting Mil/Aero and other hi-rel applications, Vishay's Tantamount Hi-Rel COTS T97 Series of solid tantalum chip capacitors are presented as the first of their kind with a 63-V rating and a capacitance of 22µF in the "F" case size. The part addresses the long-standing issue of derating, allowing designers to incorporate solid surface-mount tantalum capacitors into their hi-rel +28-V power supply designs. Available in five case sizes in capacitances from 15µF to 1,500µF, the devices come in a voltage range from 4 V to 63 V. With a dual-anode construction for low ESR values, which range from 0.015O to 0.30O at +25°C and 100 kHz. the conformal-coated capacitors have wrap-around terminations and offer high-reliability screening options including Weibull grading, as well as surge-current testing options in accordance with MIL-PRF-55365. Devices in the T97 series operate over a temperature range of -55°C to +85°C, +125°C with voltage derating. In addition to the T97 Hi-Rel series, these ratings are also available in a commercial version, the 597D series.
