GUS-QS8A-02-1743-FA Description

The GUS-QS8A-02-1743-FA 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 174K Ohm resistance and a tight 1% tolerance. With a ±50ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -55°C to +125°C (derated power range: 70°C to 125°C). The network delivers a total power rating of 0.75W (3/4W) and 0.1W (1/10W) per resistor, making it suitable for demanding circuits requiring reliability and accuracy. 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 board space.
