GUS-QS8A-02-3741-FB Description

The GUS-QS8A-02-3741-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 3.74KΩ resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and robust 0.75W (3/4W) total power rating (0.1W per resistor). Its 100V maximum voltage rating and thin-film technology make it ideal for high-reliability circuits requiring minimal drift and high accuracy.
