GUS-QS8A-02-4322-BA Description

The GUS-QS8A-02-4322-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, this device offers a 43.2KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for precision signal conditioning and voltage division. 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 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB layouts.
