GS7B031101FBT Description

The GS7B031101FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. Housed in a 14-pin narrow SOIC package, this bussed network integrates 13 thin-film resistors, each with a 1.1kΩ resistance and a tight ±1% absolute tolerance. The device operates over a temperature range of 70°C to 125°C with a low ±25ppm/°C temperature coefficient, ensuring minimal resistance drift. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction features gull-wing terminations for reliable surface-mount assembly, while the ceramic case enhances thermal and mechanical durability.
