GUS-QS8A-03-3740-DA Description

The GUS-QS8A-03-3740-DA from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing terminations, this 374Ω network offers a tight tolerance of ±0.5% and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a broad -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it excels in precision analog and digital circuits where stability and accuracy are critical. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit configurations.
