CZ-3705 - Accurate Coreless Current Sensor

Datasheet Summary

Description

CZ-3705 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, which enables the high-accuracy and high-speed current sensing.

[CZ-3705] Clearance/Creepage 8mm CZ-3705 60Arms Accurate Coreless Current Sensor 1. General Description CZ-3705 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, which enables the high-accuracy and high-speed current sensing. Coreless ultra-small surface mount package realizes the space-saving. Also, the low primary conductor resistance suppresses heat generation to achieve the 60Arms continuous current. Existing coreless current sensors have an accuracy disadvantage from degradations caused by a disturbed magnetic field. The CZ-370x series has a built-in stray magnetic field reduction function to suppress this effect.
