GUS-QS8A-02-32R4-DD Description

The GUS-QS8A-02-32R4-DD is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing termination, it offers a 32.4Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. The isolated (ISOL) circuit design ensures independent resistor performance, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its thin film technology guarantees stability and low noise, critical for precision analog and digital systems.
