Thin-Film Chip Resistor Provides Broadest Selection of Sizes and Specifications With Superior Stability Under Wide Range of Environmental Conditions
MALVERN, PENNSYLVANIA - February 8, 2002 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of a series of thin-film rectangular chip resistors that features the industry's broadest range of sizes, value ranges, and tolerances.
Vishay's TNPW series of nichrome thin-film semi-precision chip resistors is ideal for a wide range of applications requiring excellent stability, tight tolerances, and low TCR, including circuitry for navigation and avionics instrumentation, medical equipment, test equipment, automotive instrumentation, and telecommunications systems.
Features of the TNPW resistor family include very low electrical noise, tolerances as low as 0.1%, and TCR values ranging from 150 ppm/°C to as low as 15 ppm/°C. Standard resistance values range from 10 Ω to 1 MΩ. Case construction is high-quality ceramic with a metal film layer and a protective topcoat, with tin-lead (SnPb) contacts on a nickel (Ni) barrier layer.
Because Vishay's TNPW resistors are less costly than tantalum nitride thin-film solutions, designers are able to incorporate thin-film resistor technology into a wider variety of applications and end products. Vishay's wide selection of custom case sizes and extended values also means more product is available at any given time, thus reducing time-to-market for end-product manufacturers. In addition to industry-standard sizes, including 0402, 0603, 0805, 1206, and 1210, extended values are available upon request, enabling designers to enhance product performance at minimal cost.
The TNPW series of resistors provides excellent stability under both normal and harsh environmental conditions. Unlike competing nichrome thin-film resistors, which may be susceptible to corrosion under certain conditions, devices in the TNPW family of resistors are impervious to moisture. TNPW resistors conform to CECC4000 / 40400 / 40401-801, EN140400 / IEC 60115-1, and EIA 575 standards.
Samples and production quantities of the TNPW resistors are available now, with lead times of six to eight weeks.
