GUS-QS8B-02-5490-C Description

The GUS-QS8B-02-5490-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 549Ω resistance value, offering a tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, making it suitable for precision analog and digital circuits. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes board space.
