GQ8B0168R1GDT Description

The GQ8B0168R1GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 68.1Ω resistance value, offering a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and reliability in demanding environments. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a maximum operating temperature of 125°C, this network is engineered for surface-mount (SMD) applications requiring consistent performance under derated power conditions (70°C to 125°C). Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
