GUS-QS8A-01-2551-JA Description

The GUS-QS8A-01-2551-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 2.55KΩ 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 configurations. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it operates reliably across a temperature range of 70°C to 125°C, peaking at 125°C. The compact dimensions (4.9mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch enable high-density PCB layouts.
