GQ8B026490DCT Description

The GQ8B026490DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 649Ω resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C. Encased in a ceramic package, it ensures excellent thermal stability and reliability across a wide operating temperature range of 70°C to 125°C. The surface-mount design with gull-wing terminations (0.64mm pitch) facilitates compact PCB layouts, while the 0.75W (3/4W) total power rating (0.05W per resistor) supports robust performance in high-density circuits.
