GQ8A022212FFT

GQ8A022212FFT Description

The GQ8A022212FFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 8-resistor isolated network features a 22.1kΩ resistance per resistor with a 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures. Encased in a ceramic QSOP package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports moderate power dissipation. Its 100V maximum voltage rating and isolated circuit design make it suitable for high-voltage environments.
