GUS-QS8A-03-5112-BA Description

The GUS-QS8A-03-5112-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stability. This 8-resistor network features a 51.1KΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a 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 high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its 100V maximum voltage rating enhances durability in high-voltage circuits.
