GUS-QS8A-01-1181-JA Description

The GUS-QS8A-01-1181-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 1.18KΩ resistance 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 supports moderate power dissipation while maintaining stability. The thin-film technology delivers a low ±100ppm/°C temperature coefficient, making it suitable for environments with operating temperatures from 70°C to 125°C. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
