GUS-QS8B-02-4120-JF Description

The GUS-QS8B-02-4120-JF 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 412Ω resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and up to a maximum of 125°C. The ±50ppm/°C temperature coefficient enhances stability in thermally variable environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density layouts.
