GS4B012870CT Description

The GS4B012870CT 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 ±0.25% tolerance and a low ±100ppm/°C temperature coefficient. The network features a 287Ω resistance value per element, rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation. Its SOIC-C series construction ensures reliability in a compact 4.9mm × 5.99mm × 1.45mm footprint, with gull-wing terminations for secure PCB mounting. Operating across 70°C to 125°C, it supports 100V maximum voltage, making it suitable for precision analog and digital circuits.
