GUS-QS8B-02-3570-J Description

The GUS-QS8B-02-3570-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 357 Ohm resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it delivers reliable operation under moderate power conditions. The device operates across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C, making it suitable for environments with thermal fluctuations. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift, critical for stability in analog and digital signal processing.
