GUS-QS8B-01-3321-G Description

The GUS-QS8B-01-3321-G from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 3.32KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in precision circuits. The network operates over a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C at full load, making it suitable for thermally challenging environments. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a ±100ppm/°C temperature coefficient, it delivers stable performance under varying thermal conditions. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.
