GUS-QS8A-03-1003-BA Description

The GUS-QS8A-03-1003-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 isolated network features a 100K Ohm resistance value with an exceptional 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 16-pin QSOP (Molded) package, it offers a compact 4.9mm x 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating ensure robust operation in precision circuits.
