GUS-QS8A-03-1650-GD Description

The GUS-QS8A-03-1650-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 165Ω resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a 16-pin QSOP (QSOP-16) package, it offers a compact footprint with 4.9mm length, 6.02mm depth, and 1.47mm height, making it ideal for space-constrained designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of distributed loads. With a maximum voltage rating of 100V, this network is suited for analog and digital signal conditioning.
