GUS-QS8A-03-4302-GB Description

The GUS-QS8A-03-4302-GB 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 43K Ohm resistance and a tight 2% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of 70°C to 125°C (derated) and a maximum operating temperature of 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 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.
