GUS-QS8A-03-3481-CA Description

The GUS-QS8A-03-3481-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 3.48KΩ resistance value, 0.25% tolerance, and ±25ppm/°C temperature coefficient, this component ensures exceptional stability and accuracy in circuit performance. Housed in a 16-pin QSOP package, it features gull-wing terminations for reliable SMD mounting and a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height). Rated for 0.75W total power (0.1W per resistor), it operates across a 70°C to 125°C derated range, with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design allows flexible integration in precision analog and digital systems.
