GS7B029102FBT Description

The GS7B029102FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each with a 91kΩ resistance value and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in thermally challenging environments. With a ±50ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor, it delivers stable performance in precision circuits. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and 100V maximum voltage rating, making it suitable for compact, high-density PCB designs.
