CZ3A04 Description
CZ3A04 is an open-type current sensor using Hall sensors, which outputs the analog voltage proportional to the AC/DC current. Group III-V semiconductor thin film is used as the Hall sensor, enabling high-accuracy and high-speed current sensing. Coreless ultra-small surface mount package realizes space-saving. Also, the low primary conductor resistance suppresses heat generation to achieve the 50Arms continuous current. Existing coreless current sensors have an accuracy disadvantage from degradations caused by a disturbed magnetic field.
