GUS-QS8B-00-1781-JF Description

The GUS-QS8B-00-1781-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 1.78KΩ resistance value and a tight 5% tolerance, ensuring consistent performance across demanding environments. With a 0.75W (3/4W) total power rating and ±250ppm/°C temperature coefficient, it delivers stable operation under varying thermal conditions. The gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in high-density layouts, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) optimize space efficiency. Rated for 125°C maximum operating temperature, it is suitable for industrial and commercial electronics where durability and precision are critical.
