GUS-QS8B-03-9101-B Description

The GUS-QS8B-03-9101-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors with a 9.1K Ohm resistance value, offering 0.1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it ensures reliable performance in compact, high-density circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while its 100V maximum voltage rating and 125°C operating temperature range make it suitable for industrial and precision instrumentation use.
