Vishay Releases Industry's First Solid Tantalum Chip Capacitor With 63-V Rating and Molded MicroTan™ Tantalum Chip Capacitors With Industry's Lowest ESR of 1.5 Ohms for the 0603 Case Size

MALVERN, PA--(Marketwire - August 11, 2008) - New resistor products recently released by Vishay Intertechnology Inc. (NYSE: VSH) include the Tantamount® Hi-Rel COTS 63-V T97 solid tantalum chip capacitor and the TR8 series of molded MicroTan™ tantalum chip capacitors.

The Vishay Tantamount Hi-Rel COTS T97 series has been extended to offer the industry's first solid tantalum chip capacitor with a 63-V rating and a capacitance of 22 microfarads. For the first time, the new T97 device in the "F" case size allows designers to meet derating requirements of 50 % of the rated voltage in +28-V power supply designs.

Featuring a dual anode construction to ensure the lowest ESR 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 T97 series offers 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. Featuring a conformal-coating and wrap-around terminations, the capacitors offer high-reliability screening options including Weibull grading and surge current testing options in accordance with MIL-PRF-55365 in five case sizes.

Vishay's TR8 series of molded MicroTan tantalum chip capacitors provides ultra-low ESR values of 0.8 ohms (at 100 kHz and 47 microfarads) in the 0805 case size and an industry-low 1.5 ohms in the 0603 case size.

Low ESR values, combined with small 0603 and 0805 footprints, allow for greater efficiency in audio filtering and signal processing applications while requiring less PCB space. The new TR8 capacitors are intended for applications in cell phones, digital cameras, MP3 players, and other portable devices.

The devices feature lead (Pb)-free, L-shape facedown terminations for better contact to the solder pad than traditional facedown-style terminations. In addition, their rectangular molded case encapsulation helps to streamline PCB assembly.

Capacitance values for the TR8 series range from 1.0 to 220 microfarads, with standard capacitance tolerances of +/-10 % and +/-20 %. Voltage ratings range from 4 WVDC to 16 WVDC. The operating temperature range for the devices is -55 to +85 degrees Celsius, or +125 degrees Celsius with voltage derating.
