GS8B024991CBT Description

The GS8B024991CBT from TT Electronics/IRC is a high-precision ceramic thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. Packaged in a 16-pin narrow SOIC (SOIC-C Series), this bussed network integrates 15 resistors with a common 4.99KΩ value, offering an absolute tolerance of ±0.25% and a ratio tolerance of ±0.1%. Its thin-film technology ensures low noise and excellent thermal stability, with a ±50ppm/°C temperature coefficient. Rated for 0.05W (1/20W) per resistor and 0.8W total power, it operates reliably across a 70°C to 125°C derated range, with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances durability.
