GUS-QS8A-01-4122-GB Description

The GUS-QS8A-01-4122-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount technology. This 16-pin QSOP package features 8 isolated resistors, each with a 41.2KΩ resistance value and a tight 2% tolerance, ensuring reliable signal integrity in demanding circuits. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal performance. The device offers a low temperature coefficient of ±100ppm/°C, minimizing resistance drift under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint saves board space.
