CQ-236B
High-Speed Small-Sized Current Sensor
Overview
CQ-236B is an open-type current sensor using a Hall sensor which outputs the analog voltage proportional
to the AC/DC current. Quantum well ultra-thin film InAs (Indium Arsenide) is used as the Hall sensor, which
enables the high-accuracy and high-speed current sensing. Simple AI-Shell package with the Hall sensor,
magnetic core, and primary conductor realizes the space-saving and high reliability.
Features
- Uni-directional type
- Electrical isolation between the primary conductor and the sensor signal
- 5V single supply operation
- Ratiometric output
- Low variation and low temperature drift of sensitivity and offset voltage
- Low noise output: 2.3mVrms (typ.)
- Fast response time: 1μs (typ.)
- Small-sized package, halogen free
