GS4B012871CT Description

The GS4B012871CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 2.87KΩ resistance per element with an ultra-tight ±0.25% absolute tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers low noise and high reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for compact, power-sensitive designs. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in demanding circuits.
