GUS-QS8A-03-82R5-GC Description

The GUS-QS8A-03-82R5-GC from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and low thermal drift. This 8-resistor isolated network features a 82.5Ω resistance value per resistor with a tight 2% tolerance and an ultra-low ±25ppm/°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 per resistor, making it suitable for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.
