GQ8A031271GFT Description

The GQ8A031271GFT 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 1.27KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate easy surface mounting, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust performance in demanding circuits. Its isolated (ISOL) circuit design provides flexibility in circuit integration, making it ideal for analog and digital systems requiring precise voltage division or current limiting.
