GQ8A018451JFT Description

The GQ8A018451JFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values under varying thermal conditions. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers an isolated circuit design with 8.45KΩ resistance per resistor, a 5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for demanding environments. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it suitable for space-constrained designs.
