GUS-QS8A-03-1583-DB Description

The GUS-QS8A-03-1583-DB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. With a 158K Ohm resistance value and a tight 0.5% tolerance, this component ensures exceptional accuracy in circuit designs requiring stable performance. The QSOP-16 package (4.9mm x 6.02mm x 1.47mm) features gull-wing terminations for reliable soldering, while its isolated (ISOL) circuit design allows independent resistor operation. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates across a wide temperature range (-70°C to +125°C) with a low ±25ppm/°C temperature coefficient, minimizing drift in critical environments.
