GUS-QS8B-01-5490-J Description

The GUS-QS8B-01-5490-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 549Ω resistance value and a tight 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of -70°C to +125°C. The gull-wing termination and 0.64mm pitch enable secure, high-density mounting, while the 1.47mm low-profile height suits space-constrained designs.
