GUS-QS8A-02-9091-DB Description

The GUS-QS8A-02-9091-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features eight isolated 9.09KΩ resistors with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it excels in precision analog and digital circuits. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while its compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
