GUS-QS8B-00-4121-GF Description

The GUS-QS8B-00-4121-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors with a 4.12KΩ resistance value, offering a 2% tolerance and a ±250ppm/°C temperature coefficient for stable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances compactness with robust power handling. The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating and thin-film technology provide excellent noise immunity and long-term stability. Packaged in a tube, it is ideal for automated PCB assembly.
