#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% ?R after 2,000 hours of rated power at 175°C, 0.015% typical ?R 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 O to 125 kO, with any resistance value (e.g. 1K2345 vs. 1K) within this range available at any tolerance with no additional cost or lead time effect.
