GUS-QS0B-03-6490-GF Description

The GUS-QS0B-03-6490-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 649Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for compact, power-sensitive designs. Its gull-wing termination and surface-mount (SMD) configuration enable reliable PCB integration, while the tube packaging ensures safe handling and storage.
