GUS-QS8A-02-1272-DA Description

The GUS-QS8A-02-1272-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 12.7KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact designs. The device operates over a wide temperature range of -70°C to +125°C, featuring a low ±50ppm/°C temperature coefficient for stable performance under thermal stress. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm profile suits space-constrained applications.
