GUS-QS8A-01-73R2-JF Description

The GUS-QS8A-01-73R2-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-resistor isolated network features a 73.2 Ω resistance per element with a 5% tolerance and a ±100 ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -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 (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for densely populated PCBs. The isolated circuit design (ISOL) enhances signal integrity, while the thin-film technology delivers superior accuracy and low noise. Packaged in a tube for automated assembly, this active-status component is ideal for industrial and consumer electronics.
