GUS-QS8A-02-6490-FA Description

The GUS-QS8A-02-6490-FA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing termination, this surface-mount device offers a 649Ω resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for complex circuit designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. The compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) and 0.64mm terminal pitch enable high-density PCB layouts.
