Ferrite Split Bead Technology

When it comes to ferrite split bead testing, there are many different things to consider. The most important factor is the testing of the conductor because of the way the ferrite material is designed. You also need to consider the isolation properties of the test object because even with conductors that are similar, they will still have dissimilar electrical fields. A good test program for any one of the objects in your circuit needs to consider all of these factors. The circuit breaker is actually an example of a termite barrier that needs to be tested to ensure that RFI does not effect the operation.


The real reason why this test is necessary is covered in the Ground Loop portion of the Ferrite Split Bead Testing diagram. In the next section, we will discuss some ways that you can test the existence of RFI by using these ferrite beads. Needless to say, installing ferrite split beads in an attempt to solve RFI issues is technically unnecessary. However, there are some things which do not work well for RFI issues, yet enjoy a huge audience.


Among the items we can use to isolate the choke resistive path of a coaxial cable, the ferrite-carbide-tungsten coupling provides the best solution for the majority of RFI problems. For instance, the common mode current that is observed in a cable will always be equal to or smaller than the bias current and the resulting power distribution is also normally correct. However, if the common mode current suddenly changes directions, due to thermal fluctuations in the bulk of the cable, then RFI will become a significant issue. In this case, the best thing to do is to isolate the bias current using the Ferrite Split Beads.


You should first understand that Ferrite is not a single-mode wire. It is typically made up of two metals that are combined to make an extremely sturdy conductor with the highest electrical characteristic. Due to the properties of Ferrite, it is often used as an insulator in applications where a device needs to maintain a very tight signal path through the cable. Due to the inherent properties of Ferrite, it is often utilized as an antenna in communications systems where a noise filter is required to reduce radio frequency interference. For example, Ferrite is commonly used in noise reduction systems for mobile phones, Paging transmitters, satellite dishes, ATAs, power supplies, and microphones.


Another application for Ferrite is its application to the RFI suppression. To understand how this works, let us first look at how the RFI (Radio Frequency Interference) occurs. As the device moves through air or water, it will create some amount of interference. The frequency level of the unwanted emissions from nearby sources will start to interfere with the device causing what is known as 'jitter'. If the frequency level is high enough, the device will often start to shut down or freeze up.


This is where Ferrite Split Bead Technology comes into play. The Ferrite Split Beads will turn the high frequency currents from the water or air into lower frequency currents which will prevent the device from shutting down or melting down. By using a series of custom designed Ferrite Beads along with a specially designed RFID reader, the entire system can be monitored and controlled from a distance of over 160 meters.
