GUS-QS8A-03-3321-JF Description

The GUS-QS8A-03-3321-JF 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 per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it offers a compact 4.9mm x 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of moderate power loads.
