GUS-QS8B-02-4021-J Description

The GUS-QS8B-02-4021-J 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 integrates 15 resistors, each with a 4.02KΩ resistance value and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). Its thin-film technology ensures excellent stability, with a low temperature coefficient of ±50ppm/°C, making it ideal for environments with operating temperatures ranging from 70°C to 125°C. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances reliability in demanding circuits. Packaged in a tube, this non-automotive, non-PPAP compliant component is RoHS non-compliant but excels in industrial and commercial applications.
