GUS-QS8A-01-2870-GA Description

The GUS-QS8A-01-2870-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low tolerance. This 8-resistor isolated network features a 287Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it suitable for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 100V maximum voltage rating enhances durability in demanding circuits.
