GUS-QS8B-02-5490-G Description

The GUS-QS8B-02-5490-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 549Ω resistance value and a tight 2% tolerance, ensuring consistent performance. With a ±50ppm/°C temperature coefficient, it delivers excellent stability across a wide operating temperature range of 70°C to 125°C. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
