GUS-QS8A-01-9531-JA Description

The GUS-QS8A-01-9531-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 termination, this surface-mount device offers a 9.53KΩ 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 individual resistor control. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The compact 4.9mm x 6.02mm footprint and 1.47mm profile enable high-density PCB layouts.
