GUS-QS8A-02-7872-FF Description

The GUS-QS8A-02-7872-FF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. With a 78.7K Ohm resistance and a tight 1% tolerance, this device ensures reliable signal conditioning and voltage division in compact circuits. Housed in a 16-pin QSOP package, it features gull-wing terminations for secure surface-mount assembly. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in complex PCB layouts. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates across a wide temperature range (-70°C to +125°C), supported by a low ±50ppm/°C temperature coefficient for stable performance under thermal stress.
