GUS-QS0B-03-2940-JB Description

The GUS-QS0B-03-2940-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 294Ω resistance value and a 5% tolerance, providing a compact and reliable solution for bus termination, voltage division, and signal conditioning. With a 1W total power rating (0.05W per resistor) and a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating temperature range of 70°C to 125°C. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the 1.47mm low-profile height makes it suitable for space-constrained designs.
