GUS-QS8A-01-4420-GA Description

The GUS-QS8A-01-4420-GA 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 a 442Ω resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The isolated (ISOL) circuit design allows flexible configuration, while the gull-wing termination ensures secure SMD mounting. Packaged in a tube, it is optimized for automated assembly processes.
