GUS-QS8A-01-4221-GA Description

The GUS-QS8A-01-4221-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 4.22KΩ resistance, 2% tolerance, and a ±100ppm/°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 delivers reliable power dissipation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting. Its 100V maximum voltage rating and thin-film technology make it suitable for precision analog and digital circuits.
