GUS-QS8A-01-8450-GA Description

The GUS-QS8A-01-8450-GA is a high-performance 8-resistor isolated network from TT Electronics/IRC, designed for precision applications in demanding electronic circuits. This thin-film resistor network offers a 845Ω resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP (QSOP-16) package, it features gull-wing surface-mount terminals with a 0.64mm pitch, making it suitable for high-density PCB designs. The device delivers a 0.1W power rating per resistor and a total power rating of 0.75W (3/4W), with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design ensures individual resistor independence, critical for signal integrity in complex circuits.
