GUS-QS0B-03-4642-CB Description

The GUS-QS0B-03-4642-CB 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 with a 46.4KΩ resistance value, offering a tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C for stable performance across a 70°C to 125°C operating range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it ensures reliability in precision circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.
