GS7B029090GDT Description

The GS7B029090GDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 14-pin narrow SOIC device features 13 bussed resistors with a 909Ω resistance value and a tight ±2% absolute tolerance, ensuring reliable performance in precision circuits. Built with thin-film technology, it offers excellent stability with a low ±50ppm/°C temperature coefficient. The SOIC package (8.66mm × 5.99mm × 1.45mm) is optimized for surface-mount assembly, with gull-wing terminations for robust solder joints. Rated for 100V maximum voltage and 0.7W total power dissipation, it operates across a -70°C to +125°C temperature range, making it suitable for industrial and automotive environments (though not PPAP/automotive-qualified).
