GS7B029761GBT Description

The GS7B029761GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in a 14-pin narrow SOIC package, this bussed network integrates 13 thin-film resistors with a 9.76KΩ resistance value and a tight ±2% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations for reliable surface-mount assembly. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling and compactness.
