GQ8A029090FT Description

The GQ8A029090FT 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 909Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its 16-pin gull-wing SMD termination and 0.64mm terminal pitch enable compact, high-density PCB layouts. The ceramic substrate enhances thermal performance, while the isolated (ISOL) circuit design provides flexibility in circuit configurations.
