GUS-QS8B-03-6040-J Description

The GUS-QS8B-03-6040-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 604Ω resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power dissipation and compactness. The thin-film technology delivers excellent stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with operating temperatures ranging from 70°C to 125°C. Its gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating supports robust circuit protection.
