GUS-QS8A-02-3572-FF Description

The GUS-QS8A-02-3572-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, this device offers a 35.7KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, while the 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor enable reliable operation in demanding environments. With a 100V maximum voltage rating and a 125°C maximum operating temperature, this network is engineered for stability across a 70°C to 125°C derated power range. The compact 4.9mm x 6.02mm x 1.47mm footprint and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.
