GUS-QS8A-02-5112-DB Description

The GUS-QS8A-02-5112-DB 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 51.1KΩ resistance, 0.5% tolerance, and a ±50ppm/°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 0.1W per resistor, it supports high-density PCB designs while maintaining reliability. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and automated assembly.
