The Ultimate Guide to Nanocrystalline Common Mode Choke

2022-06-02

Nanocrystalline common mode choke coils (NCMCC) are a special type of electrical transformer that is used to suppress noise and electromagnetic interference (EMI) in electronic circuits. In this article, we will discuss the basics of NCMCCs, including their construction and operation, as well as some of the benefits that they offer over other types of EMI suppression devices.

Basics

Nanocrystalline common mode choke coils are composed of two or more windings of insulated wire that are wound around a core. The number of turns in the windings and the size of the core determine the inductance of the NCMCC.

The windings are typically connected to each other in a "bifilar" configuration, which means that they share a common center tap. This arrangement allows the NCMCC to be used as either an inductor or a transformer.

When used as an inductor, the NCMCC provides a low impedance path for AC current, while blocking DC current. This makes it ideal for use in power supplies and other circuits where it is necessary to filter out AC ripple.

When used as a transformer, the NCMCC can be used to step up or step down the voltage of an AC signal. This makes them useful for applications such as matching the impedance of a circuit to an external load.


Advantages

Nanocrystalline common mode choke coils offer several advantages over other types of EMI suppression devices, such as:

· Reduced size: NCMCCs are significantly smaller than other types of EMI suppression devices, such as metal oxide varistors (MOVs) and ferrite beads. This makes them ideal for use in space-constrained applications.

· Higher frequency range: NCMCCs have a much higher frequency range than MOVs and ferrite beads, making them suitable for use in high-frequency applications.

· Improved performance: NCMCCs have a lower impedance and higher inductance than MOVs and ferrite beads, resulting in improved EMI suppression performance.

Applications

Nanocrystalline common mode choke coils are used in a variety of electronic devices and circuits, such as:

· Power supplies

· AC/DC converters

· Inverters

· Switching power supplies

· Motor drives

· Audio equipment

· Telecommunications equipment

· Computers and peripherals

· Consumer electronics

Troubleshooting Nanocrystalline Common Mode Choke Coils

If you are having trouble with your nanocrystalline common mode choke coil, there are a few things that you can do to troubleshoot the problem.

Check The User Guide

The first thing that you should do is check the manufacturer's specifications for your particular coil. This will give you an idea of what the coil should be able to handle and what its limits are. It is also a good idea to check the manufacturer's website for any updates or changes to the specifications.

Check The Connections 

The next thing you should do is check all of the connections to your coil. Make sure that they are all tight and secure. Also, check to see if there are any loose wires or terminals. If there are, tighten them up or replace them.

Check The Common Mode Choke Coil Itself

Once you have checked the connections and the manufacturer's specifications, the next thing to do is check the coil itself. Make sure that there are no cracks or breaks in the coil. Also, check for any foreign objects that may be lodged in the coil. If you find anything, remove it and then test the coil again.

Test The Coil

Once you have checked all of the above, the next thing to do is test the coil. You can do this by using a multimeter to measure the resistance of the coil. The resistance should be within the manufacturer's specifications. If it is not, then you will need to replace the coil.

Replace The Nanocrystalline Common Mode Choke Coil

If you have followed all of the above steps and the coil still does not work, then you will need to replace it. You can do this by either ordering a new coil from the manufacturer or by finding a replacement coil from a third-party supplier.

Tips For Using Common Mode Choke Coils

There are a few things that you can do to make sure that your coil works properly and lasts for a long time.

Follow The Manufacturer's Specifications

The first thing that you should do is follow the manufacturer's specifications for your particular coil. This will give you the best chance of getting the longest life and best performance out of your coil.

Use Insulating Materials

If you are using your coil in an environment where there is a possibility of electrical interference, you should use insulating materials to protect it. This will help to prevent any damage to the nanocrystalline common mode choke coil and will also help to keep it working properly.

Keep The Coil Clean

Another important thing to do is to keep the common mode choke coil clean. This will help to prevent any buildup of dirt and debris on the coil which can cause it to malfunction.

Store In A Cool, Dry Place

When you are not using your nanocrystalline common mode choke coil, you should store it in a cool, dry place. This will help to keep the coil in good condition and will also help to prevent any damage from happening to it.

By following these simple tips, you can ensure that your nanocrystalline common mode choke coil will last for a long time and perform at its best.

Conclusion

Nanocrystalline common mode choke coils are a type of electrical transformer that is used to suppress noise and electromagnetic interference in electronic circuits. NCMCCs offer several advantages over other types of EMI suppression devices, including reduced size, higher frequency range, and improved performance.

NCMCCs are used in a variety of electronic devices and circuits, such as power supplies, AC/DC converters, inverters, switching power supplies, motor drives, audio equipment, telecommunications equipment, computers and peripherals, and consumer electronics.
