GUS-QS8A-02-4700-CB Description

The GUS-QS8A-02-4700-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 470Ω resistance, 0.25% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is optimized for precision analog and digital circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
