GUS-QS8A-03-8250-FB Description

The GUS-QS8A-03-8250-FB from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount PCB assemblies. This thin-film resistor network offers a 825Ω 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 of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it features gull-wing terminations for secure SMD mounting and a 0.64mm terminal pitch for high-density layouts. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding analog and digital circuits requiring low drift, high accuracy, and isolation between resistors. Packaged in tubes, it is ideal for automated assembly processes.
