GUS-QS0B-03-4751-FA Description

The GUS-QS0B-03-4751-FA 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 4.75KΩ resistance value, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, 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 × 6.02mm × 1.47mm) optimizes board space.
