GUS-QS8B-03-3742-B Description

The GUS-QS8B-03-3742-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors with a 37.4KΩ 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), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for precision analog and digital circuits. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes board space.
