GUS-QS8A-03-2612-FB Description

The GUS-QS8A-03-2612-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 26.1KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it delivers robust performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the 1.47mm low-profile height suits space-constrained applications.
