GQ8A031212FBT Description

The GQ8A031212FBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers 12.1KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this 16-pin gull-wing SMD device is ideal for space-constrained PCB designs requiring reliable, high-density resistor arrays. Its isolated (ISOL) circuit design eliminates crosstalk, making it suitable for precision analog and mixed-signal systems.

GQ8A031212FBT Features
