GS4B028200CT Description

The GS4B028200CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in an 8-pin narrow SOIC (SOIC-C series), this 7-resistor bussed network features a 820Ω resistance value with an ultra-tight ±0.25% absolute tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures stability and reliability, while the ceramic case provides excellent thermal performance. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration.
