GQ8A012210JFT Description

The GQ8A012210JFT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 221 Ohm, 5% tolerance network offers a ±100ppm/°C temperature coefficient, ensuring reliable operation across a 70°C to 125°C derated power range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for surface-mount (SMD) applications in demanding environments. The 16-pin gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its isolated (ISOL) circuit design enhances signal integrity in multi-channel systems.
