GS7B034420CT Description

The GS7B034420CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed configuration integrates 13 resistors with a 442Ω resistance value and an ultra-tight ±0.25% tolerance. Built with thin-film technology, it delivers exceptional stability with a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Its ceramic case and gull-wing termination provide robust mechanical and thermal performance for surface-mount applications.
