GQ8A031272FFT

GQ8A031272FFT Description

The GQ8A031272FFT 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, this 16-pin SMD component offers a 12.7KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, while the ceramic construction enhances thermal and mechanical durability.
