GQ8B0278R7DCT Description

The GQ8B0278R7DCT 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 78.7 Ω resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±50 ppm/°C. Encased in a ceramic package, it ensures excellent thermal stability and reliability across an operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it supports high-density PCB designs while maintaining performance under derated power conditions.
