GUS-QS8B-01-4750-B Description

The GUS-QS8B-01-4750-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 475 Ω resistance value, offering 0.1% tolerance and a ±100 ppm/°C temperature coefficient for exceptional stability. Rated for 0.75W (3/4W) total power and 0.05W (1/20W) per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
