GUS-QS8A-03-6490-DB Description

The GUS-QS8A-03-6490-DB 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 649Ω resistance value and a tight 0.5% tolerance, ensuring consistent performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability applications. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint saves board space.
