GUS-QS8B-01-9090-B Description

The GUS-QS8B-01-9090-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package features 15 resistors with a 909Ω resistance value, offering an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power (0.05W per resistor), it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.
