GQ8A014120CT Description

The GQ8A014120CT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it features a 412Ω resistance value with an ultra-tight ±0.25% tolerance and a low ±100ppm/°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 (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) is engineered for reliability in demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical robustness.
