GUS-QS8B-00-1871-G Description

The GUS-QS8B-00-1871-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in compact surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 1.87KΩ resistance value and a tight 2% 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 performance. The ±250ppm/°C temperature coefficient guarantees stability under thermal stress, while the 100V maximum voltage rating suits moderate-voltage circuits. Its gull-wing termination and 0.64mm terminal pitch enable robust PCB mounting in space-constrained designs.
