GUS-QS0B-03-2942-CA Description

The GUS-QS0B-03-2942-CA 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 29.4KΩ resistance value, a tight 0.25% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it delivers reliable performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low-profile height suits space-constrained applications. Packaged in a tube, it is ideal for automated placement.
