MagnTek· New product | is suitable for the new generation of 0~±300A open-loop current sensor module -MTC921
The MTC921 chip is MagnTek's new generation of open-loop current sensor modules based on the Hall effect principle, which can be widely used in AC or DC current detection in industrial, commercial and communication systems.
| Packaging form
| Product Introduction
The MTC921 consists of a high-precision, low-noise, and low-temperature drift linear Hall IC, a magnetic core, and a built-in low insertion resistance current conductor path. The external current flowing through this low resistance current conductor path will generate a collision field, which the chip converts into a voltage signal output proportional to the input current. Due to the use of magnetic cores inside the module, it can effectively suppress the interference of external common mode magnetic fields on the module and improve accuracy in magnetic noise environments.
