Product Overview
The CQ-209D is an open-type current sensor utilizing an ultra-thin film InAs Quantum Well Hall sensor for high-accuracy and high-speed AC/DC current sensing. Its compact AI-Shell package integrates the Hall sensor, magnetic core, and primary conductor, offering space-saving and high reliability. Key features include electrical isolation, 5V single supply operation, ratiometric output, low variation and temperature drift in sensitivity and offset voltage, low noise output, fast response time, and a small-sized surface mount package that is halogen-free. It is suitable for applications requiring precise current monitoring.
