GUS-QS8A-02-4222-JF Description

The GUS-QS8A-02-4222-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 8 isolated resistors, each with a 42.2KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers robust performance in compact designs. The device operates over a wide temperature range of -70°C to +125°C, featuring a low ±50ppm/°C temperature coefficient for stable resistance under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density layouts.
