Nanocrystalline Common Mode Choke: Enhancing EMI Suppression and Performance


A nanocrystalline common mode choke is designed to filter out electromagnetic or radio frequency interference. As the name implies, it is made from nanocrystalline cores.

Here at Transmart, we are a trusted transformer core manufacturer that takes pride in the production and supply of high-quality nanocrystalline common mode chokes. If you’re looking for a reliable nanocrystalline core manufacturer, look no further than Transmart. Today, we will look into nanocrystalline common mode chokes in greater detail.

Introducing Nanocrystalline Common Mode Chokes

As the name suggests, nanocrystalline common mode chokes are a type of common mode choke made from nanocrystalline cores. These cores are designed to filter outside interference and allow low-frequency direct currents to pass through electrical circuits. Nanocrystalline common mode chokes consist of two coils wound on a single nanocrystalline core to suppress interference and prevent signal pollution.

As we’ve already highlighted, the purpose of nanocrystalline common mode chokes is to suppress unwanted common mode noise or interference, which can affect the performance of electronic devices. Nanocrystalline cores are good at supressing common-mode noise thanks to their unique magnetic properties.

Nanocrystalline common mode chokes are often used in applications like power electronic, data communication, and industrial automation to ensure that signals remain clean and interference-free. These common mode chokes are designed to improve the reliability and performance of electronic systems.

Nanocrystalline Common Mode Chokes vs. Ferrite Common Mode Chokes

Both nanocrystalline and ferrite materials are used in common mode chokes thanks to their ability to reduce electromagnetic interference. The major differences between the two types of chokes boil down to the materials used and characteristics. Nanocrystalline common mode chokes are composed of nanoscale crystalline grains, which are known to offer high permeability and low core losses. On the other hand, ferrite common mode chokes are made from ceramic materials. These materials provide high magnetic permeability and have higher core losses compared to chokes made from nanocrystalline cores. Your choice between the two types of common mode chokes depends on your specific project.

Nanocrystalline Common Mode Chokes vs. Amorphous Common Mode Chokes

There are several differences that distinguish these two types of common mode chokes. These include—core material, efficiency, and size.  Nanocrystalline common mode chokes are made up of nanoscale crystalline grains, while amorphous common mode chokes consist of non-crystalline materials. Amorphous common mode chokes exhibit high initial permeability, but they tend to have higher core losses compared to their nanocrystalline counterparts.

When it comes to efficiency, amorphous common mode chokes are efficient at certain frequencies but may not match the overall efficiency of nanocrystalline cores. In terms of size, crystalline cores allow for smaller and more compact designs. This is the reason why they are preferred for space-constrained applications. On the other hand, amorphous common mode chokes may require larger sizes to achieve the same performance.
