GUS-QS8A-03-2212-DA Description

The GUS-QS8A-03-2212-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 22.1KΩ resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. Rated for 0.75W (3/4W) total power and 100V maximum voltage, it combines reliability with precision in industrial and instrumentation circuits.

GUS-QS8A-03-2212-DA Features
