GUS-QS8A-02-9091-FB Description

The GUS-QS8A-02-9091-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 9.09KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum. Its ±50ppm/°C temperature coefficient guarantees stability in thermally variable environments. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm × 6.02mm × 1.47mm footprint saves board space.
