GUS-QS8A-03-2941-FF Description

The GUS-QS8A-03-2941-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 2.94KΩ resistance value per resistor with a tight 1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while its thin-film technology provides superior accuracy and long-term stability compared to thick-film alternatives.
