GUS-QS0B-03-1022-D Description

The GUS-QS0B-03-1022-D 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 10.2KΩ resistance, a tight 0.5% tolerance, and a low ±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, it offers reliable operation in compact, high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and automated assembly. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
