GUS-QS8B-02-4990-D Description

The GUS-QS8B-02-4990-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 499Ω resistance value, offering a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, it ensures reliable performance in thermally challenging environments. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its compact dimensions (4.9mm × 6.02mm × 1.47mm) save board space.
