GQ8A011800GFT Description

The GQ8A011800GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 180Ω resistance value per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Encased in a ceramic QSOP package, it offers superior thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable 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 circuits. With a 100V maximum voltage rating, it is ideal for industrial and instrumentation applications requiring isolation and precision.
