GUS-QS8A-01-1781-JB Description

The GUS-QS8A-01-1781-JB 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 8 isolated resistors, each with a 1.78KΩ resistance and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining stability across a wide temperature range (70°C to 125°C derated, 125°C max). The ±100ppm/°C temperature coefficient enhances reliability in thermally variable environments. Its gull-wing termination and 0.64mm terminal pitch facilitate robust soldering and high-density layouts.
