GUS-QS0B-03-4302-FC Description

The GUS-QS0B-03-4302-FC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package features 19 resistors, each with a 43K Ohm resistance and a tight 1% tolerance, ensuring reliable performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for compact, high-density designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the 1.47mm low-profile height optimizes space efficiency. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
