CQ3301 and CQ3303 Coreless Current Sensor

AKM Semiconductor offers the world's smallest coreless current sensor that corresponds to safety standards

Image of AKM Semiconductor CQ3301 and CQ3303 Cordless Current SensorAKM's CQ-3301 and CQ-3303 are open-type current sensors using a Hall sensor which outputs the analog voltage proportional to the AC / DC current. Quantum's ultra-thin-film Indium Arsenide (InAs) is used as the Hall sensor, which enables high-accuracy and high-speed current sensing. The coreless surface-mount package realizes the space-savings.
