GS4B011871GFT Description

The GS4B011871GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications. This thin-film ceramic resistor network offers a 1.87KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor make it suitable for stable operation across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly.
