GUS-QS8A-03-6490-JF Description

The GUS-QS8A-03-6490-JF 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 features 8 isolated resistors, each with a 649Ω resistance value and a 5% tolerance. With a power rating of 0.75W (3/4W) and a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range (70°C to 125°C). The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances reliability in demanding circuits. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
