GS4B027500CT Description

The GS4B027500CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Built with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and a tight ±0.25% absolute tolerance. The network features a 750Ω resistance value per element, rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation. Its 100V maximum voltage rating and 125°C maximum operating temperature make it suitable for industrial and instrumentation use. The gull-wing termination ensures reliable solderability, while the SOIC-C series ceramic case enhances thermal performance and durability.
