GUS-QS8B-03-7321-D Description

The GUS-QS8B-03-7321-D is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package features 15 resistors with a 7.32KΩ resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. The network delivers a 0.75W (3/4W) total power rating, with each resistor rated for 0.05W (1/20W). Its gull-wing termination ensures reliable solderability, while the QSOP case provides a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. Rated for 100V maximum voltage and operating from 70°C to 125°C, this non-automotive, non-PPAP compliant component is suited for industrial and commercial electronics.
