GUS-QS8A-03-3741-FA Description

The GUS-QS8A-03-3741-FA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. With a 3.74KΩ resistance value, 1% tolerance, and ±25ppm/°C temperature coefficient, this device ensures stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package, it features gull-wing SMD termination for reliable surface-mount assembly. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for complex circuit configurations. Its 0.75W (3/4W) total power rating and 100V maximum voltage rating ensure robustness in demanding environments.
