GQ8A028451JFT Description

The GQ8A028451JFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and low thermal drift. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers an isolated configuration (ISOL) with a resistance value of 8.45KΩ (±5%) and a ±50ppm/°C temperature coefficient, ensuring reliable 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 maximum voltage rating of 100V, it is engineered for demanding circuit designs. 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 layouts.
