GUS-QS8A-01-6651-JA Description

The GUS-QS8A-01-6651-JA 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 6.65KΩ resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for complex circuit designs requiring reliable signal isolation. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates efficiently across a wide temperature range of 70°C to 125°C, peaking at 125°C maximum. The compact 4.9mm × 6.02mm × 1.47mm footprint and ±0.1mm height tolerance ensure compatibility with high-density PCB layouts.
