GUS-QS8A-03-1003-FA Description

The GUS-QS8A-03-1003-FA is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance and low thermal drift. This 8-resistor isolated network features a 100K Ohm resistance per element with a tight 1% tolerance and an ultra-low ±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 with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The 100V maximum voltage rating and thin-film technology provide excellent stability and low noise, ideal for sensitive analog and digital circuits.
