GUS-QS8A-02-2740-DA Description

The GUS-QS8A-02-2740-DA is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. With a 274 Ω resistance value per resistor and a tight 0.5% tolerance, this component ensures reliable signal conditioning, voltage division, and impedance matching in compact circuits. The QSOP-16 package (4.9 × 6.02 × 1.47 mm) features gull-wing terminations for secure PCB mounting, while its isolated (ISOL) circuit design allows independent resistor operation. Rated for 0.75W total power dissipation (0.1W per resistor) and a wide temperature range of -70°C to +125°C, this network is engineered for stability in harsh environments.
