GUS-QS0B-03-2551-FD Description

The GUS-QS0B-03-2551-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 2.55KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it combines reliability with compactness, making it ideal for space-constrained designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low profile enhances compatibility with high-density layouts.
