GUS-QS0B-03-6811-D Description

The GUS-QS0B-03-6811-D 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 6.81KΩ resistance value, offering a tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, this component ensures reliable performance in thermally challenging environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
