GUS-QS0B-03-6491-FD Description

The GUS-QS0B-03-6491-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 6.49KΩ resistance value, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in compact, high-density circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate seamless PCB assembly, while the 1.47mm low-profile height makes it ideal for space-constrained designs.
