GUS-QS8A-03-3321-FA Description

The GUS-QS8A-03-3321-FA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 3.32KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its rectangular package (4.9mm x 6.02mm x 1.47mm) optimizes board space efficiency.
