GUS-QS8B-03-4301-G Description

The GUS-QS8B-03-4301-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device integrates 15 resistors, each with a 4.3KΩ resistance value and a tight 2% tolerance. It operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 0.75W (3/4W), with 0.05W (1/20W) per resistor. The ±25ppm/°C temperature coefficient ensures stability in varying thermal conditions, while the 100V maximum voltage rating and gull-wing termination enhance reliability in demanding circuits.

GUS-QS8B-03-4301-G Features
