GUS-QS8A-03-4220-JA Description

The GUS-QS8A-03-4220-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features isolated resistors with a 422Ω resistance value, 5% tolerance, and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining reliability. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
