GUS-QS8A-02-2212-CA Description

The GUS-QS8A-02-2212-CA 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 22.1KΩ resistors with an ultra-tight tolerance of ±0.25% and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. 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 pitch facilitate reliable PCB assembly, while its compact 4.9mm × 6.02mm × 1.47mm footprint saves board space. Packaged in a tube, it is ideal for automated placement.
