GUS-QS8B-02-1271-GF Description

The GUS-QS8B-02-1271-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 1.27KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, making it suitable for environments with thermal stress. Its ±50ppm/°C temperature coefficient guarantees minimal resistance drift, while the 0.75W (3/4W) total power rating (0.05W per resistor) supports robust power handling. The gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMD processes.
