GUS-QS0B-03-3091-FD Description

The GUS-QS0B-03-3091-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 3.09KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.05W (1/20) power rating per resistor and a total power rating of 1W, it delivers reliable power dissipation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its rectangular, RoHS non-compliant construction meets industrial standards.
