GUS-QS8A-03-1822-FB Description

The GUS-QS8A-03-1822-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 18.2KΩ resistance value and a tight 1% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range (70°C to 125°C). The network offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for demanding circuits requiring reliable power dissipation. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes space efficiency.
