GUS-QS0B-03-4322-FA Description

The GUS-QS0B-03-4322-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP device integrates 19 resistors, each with a 43.2KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it excels in compact, high-density circuits. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while its 6.02mm × 8.66mm footprint and 1.47mm profile optimize space efficiency.
