GQ8A021131DT Description

The GQ8A021131DT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 1.13KΩ resistance per resistor with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. The device features a 16-pin gull-wing SMD termination, making it suitable for automated PCB assembly. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it excels in precision analog and mixed-signal circuits. The ceramic substrate enhances thermal stability, while the isolated (ISOL) circuit design minimizes crosstalk.
