GUS-QS8A-03-3922-FB Description

The GUS-QS8A-03-3922-FB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. With a 39.2KΩ resistance value, 1% tolerance, and ±25ppm/°C temperature coefficient, this device ensures stable and reliable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact 4.9mm x 6.02mm footprint and a low 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating ensure robust handling of distributed loads.
