GQ8B021781JT Description

The GQ8B021781JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 1.78KΩ resistance value and a 5% tolerance, offering a compact and reliable solution for space-constrained designs. Encased in a ceramic package, it ensures excellent thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination style facilitates easy surface-mount (SMD) assembly, while the 0.64mm terminal pitch enhances PCB layout flexibility. With a total power rating of 0.75W (3/4W) and ±50ppm/°C temperature coefficient, this network is engineered for stable performance across a 70°C to 125°C derated power range.
