GUS-QS8A-03-1133-JF Description

The GUS-QS8A-03-1133-JF 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 features 8 isolated resistors, each with a 113KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, derated for optimal thermal performance. The ±25ppm/°C temperature coefficient guarantees stability in fluctuating environments, while the 100V maximum voltage rating supports robust circuit protection.
