GUS-QS0B-03-4530-C Description

The GUS-QS0B-03-4530-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP surface-mount device integrates 19 resistors with a 453Ω resistance value, offering a tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated PCB assembly processes. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital circuits.
