GQ8A024990GFT Description

The GQ8A024990GFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 499Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining reliability. The isolated (ISOL) circuit design allows independent resistor operation, making it versatile for complex circuit layouts. Its gull-wing termination ensures secure PCB mounting, and the ceramic construction enhances thermal and mechanical durability.
