GQ8A0249R9GGT Description

The GQ8A0249R9GGT 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 49.9Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design provides individual resistor functionality, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding environments. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, and the 100V maximum voltage rating enhances versatility in high-voltage circuits.
