Low temperature drift and low noise output current sensor AKM CQ206A in compact AI Shell package
Product Overview
The CQ-206A is an open-type current sensor utilizing a quantum well ultra-thin film InAs Hall sensor, enabling high-accuracy and high-speed AC/DC current sensing. Its AI-Shell package integrates the Hall sensor, magnetic core, and primary conductor for space-saving and high reliability. Key features include bidirectional operation, electrical isolation, 5V single supply, ratiometric output, low variation in sensitivity and offset voltage, low temperature drift, low noise output (2.1mVrms max.), and a fast response time of 1s (typ.). The compact, halogen-free package makes it suitable for various applications requiring precise current monitoring.
