GQ8A022940GGT Description

The GQ8A022940GGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it features 294Ω 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. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.
