GUS-QS8A-02-3302-DA Description

The GUS-QS8A-02-3302-DA is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. Featuring a 33K Ohm resistance per resistor with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, this component ensures stable performance across a wide temperature range (70°C to 125°C). Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) while delivering 0.1W per resistor and a total power rating of 0.75W. Its isolated (ISOL) circuit design and 100V maximum voltage rating make it suitable for precision analog and digital circuits.
