GQ8A028871FFT

GQ8A028871FFT Description

The GQ8A028871FFT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding circuit isolation (ISOL) applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers an 8.87KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (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 analog and digital circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it suitable for space-constrained designs.
