GUS-QS8A-03-8450-GA Description

The GUS-QS8A-03-8450-GA 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 SMD termination, this device offers a 845Ω resistance per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and impedance matching. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a 70°C to 125°C derated range, peaking at 125°C maximum. The compact 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch enable high-density PCB layouts.
