GQ8B022742GT Description

The GQ8B022742GT 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, each with a 27.4KΩ resistance value and a tight 2% tolerance. Built on a ceramic substrate, it offers excellent thermal stability with a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The network is rated for 0.75W (3/4W) total power dissipation, with each resistor handling 0.05W (1/20W). Its gull-wing termination and surface-mount design make it ideal for automated PCB assembly.
