GUS-QS8A-02-1801-FF Description

The GUS-QS8A-02-1801-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 1.8KΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers excellent space efficiency for densely populated PCBs. The device supports a maximum voltage rating of 100V and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor, making it suitable for power-sensitive designs. Its thin-film technology provides superior accuracy, low noise, and long-term reliability compared to thick-film alternatives.
