GUS-QS8B-02-2870-J Description

The GUS-QS8B-02-2870-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 287 Ω resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.05W per resistor), it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal performance. The ±50ppm/°C temperature coefficient guarantees stability in fluctuating environments, while the 100V maximum voltage rating and gull-wing termination facilitate robust, high-density circuit designs.
