GUS-QS8A-03-2742-DA Description

The GUS-QS8A-03-2742-DA is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. It features a 27.4KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package with gull-wing terminations, this isolated (ISOL) network offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for precision analog and digital circuits. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch enable high-density PCB layouts.
