GQ8A034990FFT Description

The GQ8A034990FFT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for surface-mount applications. Encased in a 16-pin QSOP ceramic package, it offers 499Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The isolated (ISOL) circuit design provides individual resistor functionality, making it ideal for precision signal conditioning. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
