GUS-QS8A-02-4870-FB Description

The GUS-QS8A-02-4870-FB 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 terminations, this surface-mount device offers a 487Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its 0.75W (3/4W) total power rating and 0.1W per resistor ensure reliable operation in demanding environments, supported by a wide temperature range of 70°C to 125°C (derated) and a maximum operating temperature of 125°C. The compact dimensions (4.9mm x 6.02mm x 1.47mm) and ±0.1mm height/length tolerances make it ideal for space-constrained PCB designs.
