GUS-QS8B-03-4990-J Description

The GUS-QS8B-03-4990-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 499Ω resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating temperature range of 70°C to 125°C. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 0.64mm terminal pitch enable compact, high-density layouts.
