GUS-QS8B-03-6802-D Description

The GUS-QS8B-03-6802-D is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. It features 15 resistors in a 16-pin QSOP package, each with a 68KΩ resistance value and an ultra-tight 0.5% tolerance. The network delivers a total power rating of 0.75W (3/4W) and operates within a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. Its ±25ppm/°C temperature coefficient ensures stable performance under thermal stress. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint saves board space.
