GUS-QS0B-03-2872-FF Description

The GUS-QS0B-03-2872-FF 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 28.7KΩ resistance value, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 1W total power rating (0.05W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in compact, high-density circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the rectangular QSOP case (8.66mm x 6.02mm x 1.47mm) optimizes board space utilization.
