GUS-QS8B-03-8451-C Description

The GUS-QS8B-03-8451-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 15 resistors with a 8.45KΩ resistance value, offering a tight 0.25% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it ensures reliable performance in high-density circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) optimize space efficiency. Rated for 125°C maximum operating temperature, it supports derated power up to 70–125°C, making it suitable for thermally challenging environments.
