GUS-QS8A-03-1652-BB Description

The GUS-QS8A-03-1652-BB from TT Electronics/IRC is a high-precision 16.5KΩ thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. Housed in a 16-pin QSOP package with gull-wing SMD termination, this 8-resistor isolated network offers a 0.1% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably within a -70°C to +125°C derated power range, making it suitable for harsh environments. The compact 4.9mm × 6.02mm × 1.47mm footprint and 1.63mm seated height enable high-density PCB layouts.
