GQ8B026190GT Description

The GQ8B026190GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. Encased in a ceramic QSOP package, this 16-pin SMD component integrates 15 resistors with a 619Ω resistance value, offering a tight 2% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.05W (1/20W) per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its gull-wing termination and 0.64mm terminal pitch ensure secure surface mounting, while the ceramic construction enhances thermal stability and durability.
