GQ8A022261GT Description

The GQ8A022261GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 2.26KΩ resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust performance in demanding circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it ideal for signal conditioning, voltage division, and isolation tasks.
