GUS-QS8A-02-1581-DA Description

The GUS-QS8A-02-1581-DA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerances and stable performance. This 16-pin QSOP surface-mount device integrates 8 isolated resistors, each with a 1.58KΩ resistance value and an exceptional ±0.5% tolerance. With a ±50ppm/°C temperature coefficient, it ensures minimal resistance drift across a wide operating temperature range of 70°C to 125°C. The network offers a total power rating of 0.75W (3/4W) and 0.1W (1/10W) per resistor, making it suitable for precision analog and digital circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
