GUS-QS8B-03-5110-B Description

The GUS-QS8B-03-5110-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 511Ω resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it maintains stable performance across a wide operating temperature range of 70°C to 125°C. The network delivers a total power rating of 0.75W (3/4W) and 0.05W (1/20W) per resistor, making it suitable for low-power, high-density designs. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained environments.
