GQ8A022801GT Description

The GQ8A022801GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 2.8K Ohm resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed 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 easy surface mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate power dissipation.
