GUS-QS8B-03-3741-B Description

The GUS-QS8B-03-3741-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP surface-mount device integrates 15 resistors with a 3.74KΩ resistance value, offering a tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, it ensures reliable performance in precision circuits. The gull-wing termination and QSOP package (4.9mm x 6.02mm x 1.47mm) facilitate compact PCB layouts, while its 70°C to 125°C derated power range and 125°C maximum operating temperature make it suitable for industrial environments.
