GUS-QS8B-03-4121-GF Description

The GUS-QS8B-03-4121-GF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. It features 15 resistors in a 16-pin QSOP package, each with a 4.12KΩ resistance and a tight 2% tolerance. The network operates within a wide temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load. With a ±25ppm/°C temperature coefficient, it ensures stable performance in thermally variable environments. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits.

GUS-QS8B-03-4121-GF Features
