Product Specification
| Voltage - Supply | 4.5V~5.5V | Description | SMD Current Sensors RoHS |
| Mfr. Part # | CQ209B | Package | SMD |
| Model Number | CQ209B |
The CQ-209B is an open-type current sensor that utilizes a quantum well ultra-thin film InAs Hall sensor to provide high-accuracy and high-speed AC/DC current sensing. Its analog voltage output is directly proportional to the measured current. The integrated AI-Shell package, containing the Hall sensor, magnetic core, and primary conductor, ensures a space-saving and highly reliable solution. Key features include electrical isolation, 5V single supply operation, ratiometric output, low variation in sensitivity and offset voltage, low noise, and a fast response time. It is suitable for applications requiring precise and rapid current monitoring.
