GS8B011272CBT Description

The GS8B011272CBT from TT Electronics/IRC is a high-precision ceramic thin-film resistor network designed for demanding applications requiring stable performance under elevated temperatures. Housed in a 16-pin narrow SOIC package, this bussed (BUS) configuration integrates 15 resistors with a 12.7KΩ resistance 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 ±100ppm/°C temperature coefficient. Rated for 0.05W (1/20) per resistor and 0.8W total power dissipation, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances durability.
