The T97 series is designed for safety-critical applications

Tag : capacitor
The Vishay Tantamount Hi-Rel COTS T97 series has been extended tooffer the industry's first solid tantalum chip capacitor with a63-V rating and a capacitance of 22 microfarads. For the firsttime, the new T97 device in the "F" case size allows designers tomeet derating requirements of 50 % of the rated voltage in +28-Vpower supply designs.
Featuring a dual anode construction to ensure the lowest ESR in itsclass, 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 andradar systems, avionics, and space-based electronics.
The T97 series offers designers a wide array of ratings not foundin available MIL specifications, combining the flexibility andconvenience of a commercial product with the reliability needed indemanding applications. Featuring a conformal-coating andwrap-around terminations, the capacitors offer high-reliabilityscreening options including Weibull grading and surge currenttesting options in accordance with MIL-PRF-55365 in five casesizes.
Vishay's TR8 series of molded MicroTan tantalum chip capacitorsprovides ultra-low ESR values of 0.8 ohms (at 100 kHz and 47microfarads) in the 0805 case size and an industry-low 1.5 ohms inthe 0603 case size.
Low ESR values, combined with small 0603 and 0805 footprints, allowfor greater efficiency in audio filtering and signal processingapplications while requiring less PCB space. The new TR8 capacitorsare intended for applications in cell phones, digital cameras, MP3players, and other portable devices.
The devices feature lead (Pb)-free, L-shape facedown terminationsfor better contact to the solder pad than traditionalfacedown-style terminations. In addition, their rectangular moldedcase encapsulation helps to streamline PCB assembly.
Capacitance values for the TR8 series range from 1.0 to 220microfarads, with standard capacitance tolerances of +/-10 % and+/-20 %. Voltage ratings range from 4 WVDC to 16 WVDC. Theoperating temperature range for the devices is -55 to +85 degreesCelsius, or +125 degrees Celsius with voltage derating.
