GUS-QS8A-03-5762-DA Description

The GUS-QS8A-03-5762-DA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 8-resistor isolated network features a 57.6KΩ resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. With a 0.1W power rating per resistor and 0.75W total power dissipation, it balances performance and reliability in precision circuits.
