GUS-QS8A-02-3571-GB Description

The GUS-QS8A-02-3571-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 3.57KΩ resistance value with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor), making it suitable for power-sensitive designs. The gull-wing termination and surface-mount (SMD) design facilitate easy PCB integration, while its 100V maximum voltage rating enhances reliability in high-voltage circuits.

GUS-QS8A-02-3571-GB Features
