GUS-QS8B-03-3921-GF Description

The GUS-QS8B-03-3921-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 3.92KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating temperature range of -70°C to +125°C. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.
