GUS-QS0B-03-5101-FB Description

The GUS-QS0B-03-5101-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 5.1KΩ resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it maintains stability across a wide operating range (70°C to 125°C). The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for moderate-power applications. Packaged in a tube, it is ideal for automated assembly processes.
