CQ3301 and CQ3303 Coreless Current Sensor

By AKM Semiconductor Inc 60

AKM'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.
