GUS-QS8B-00-2491-G Description

The GUS-QS8B-00-2491-G is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 2.49KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness. The thin-film technology delivers excellent stability, with a ±250ppm/°C temperature coefficient, making it suitable for environments with operating temperatures ranging from 70°C to 125°C. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMD processes.
