GUS-QS8A-03-3321-FF Description

The GUS-QS8A-03-3321-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 3.32KΩ resistance value with a tight 1% tolerance and a low ±25ppm/°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 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, making it ideal for space-constrained designs requiring reliable power dissipation. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface-mount assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.
