GUS-QS0B-02-4531-B Description

The GUS-QS0B-02-4531-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP package integrates 19 resistors, each with a 4.53KΩ resistance value and an exceptional 0.1% tolerance, ensuring minimal deviation in critical circuits. With a ±50ppm/°C temperature coefficient, it delivers reliable operation across a wide temperature range (70°C to 125°C). The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
