GUS-QS8A-03-7870-BB Description

The GUS-QS8A-03-7870-BB is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. It features an isolated (ISOL) circuit design with a 787Ω resistance value per resistor, offering 0.1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Encased in a 16-pin QSOP package with gull-wing terminations, this network delivers 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably across a wide temperature range of -70°C to +125°C. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and ±0.1mm height tolerance ensure compatibility with high-density PCB layouts.
