GUS-QS8A-02-4121-FF Description

The GUS-QS8A-02-4121-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.12KΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C (derated). Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount (SMD) assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.
