Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay Foil Resistors (VFR) brand's FRST series (0603-2512) of ultra-high-precision Bulk Metal ® Z1-Foil commercial off-the-shelf (COTS) resistors and Micro-Measurements brand's high-resistance miniature foil strain gages have been selected for Electronic Design’s “Top 101 Components.” The annual list compiles the 101 most popular components from the previous year among readers of the magazine’s Products of the Week newsletter.
#71 — FRST Series Ultra-High-Precision Bulk Metal Z1-Foil Resistors
The FRST series of wraparound, COTS surface-mount chip resistors are designed for high-temperature applications up to +200°C. The devices provide a load-life stability of 0.02% ΔR after 2,000 hours of rated power at 175°C, 0.015% typical ΔR after 1,000 hours at 85°C/85% relative humidity, and a low TCR of ±2.5 ppm/°C from -55°C to +175°C (25°C ref). The FRST series is optimized for a variety of industrial, alternative energy, resistance temperature detector (RTD), military, aerospace, medical, Li-ion battery charging, down-hole, and oil well applications requiring resistors to have a minimal drift from their initial values when operating above +175°C and in humid environments.
The FRST devices are built on next-generation Z1-Foil technology, for which the main advantage is an increased insensitivity to temperature and humidity changes. A solid monolithic alloy element is matched to the substrate, forming a single interdependent structure with balanced temperature characteristics for an unusually low and predictable TCR and load life stability. Offered in six chip sizes from 0603 to 2512, the FRST series features a wide resistance range from 5 Ω to 125 kΩ, with any resistance value (e.g. 1K2345 vs. 1K) within this range available at any tolerance with no additional cost or lead time effect.Link to product datasheet: http://www.vishaypg.com/doc?63235 (FRST series) Further information about the FRST series and other Vishay Foil Resistors products is available at www.vishayfoilresistors.com.

VPG’s high-resistance miniature foil strain gages open up new transducer design opportunities by combining various sizes with resistance values from the standard 350 Ω up to 20 kΩ, at a very tight resistance tolerance. Together with the excellent gage-to-gage matching, this ensures excellent circuit stability with temperature variations and reduction of zero shifts.
