GUS-QS8B-03-1101-B Description

The GUS-QS8B-03-1101-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 1.1KΩ resistance and an ultra-tight tolerance of ±0.1%, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide -70°C to +125°C operating range, making it suitable for environments with thermal fluctuations. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
