Ferrite Cores - Cables and WiringSB28B0642 is a ferrite core commonly used in the current electronic industry. Ferrite cores are a type of magnetic materials produced by an industrial process. Ferrite cores are made from ferrite, which is a ceramic material that is composed of iron oxides. The two most common types of ferrite cores are cores formed from nickel-zinc ferrite (NiZn) and cores formed from manganese-zinc ferrite (MnZn).Ferrite cores are primarily used in the design of communications, energy conversion, and networking applications. The biggest advantage of using ferrite cores is their ability to reduce electromagnetic interference (EMI). EMI is a form of energy that can interfere with the signal of an electronic device, which can cause it to be affected and possibly malfunction. By using ferrite cores in the circuit design, EMI can be reduced or limited, ensuring that the circuit board functions correctly.The SB28B0642 ferrite core is a small size core, with a diameter of 28mm and a height of 6mm. It has a high permeability value (maximum permeability of 18,000) and an inductance of 2.75mH. These characteristics make the SB28B0642 ferrite core especially suitable for use in broadband communications applications.The working principle of the ferrite core can be explained with the analogy of a tin can filled with iron filings. If an electrical current is passed through the core, the iron filings will be magnetized, forming magnetic lines of force. Similarly, when a ferrite core is exposed to an electrical current, the electrons will cause a magnetic field to form. This magnetic field has two components; an inductance component and a resistance component.The inductance component is caused by the electrons in the wire being forced to move in circles around the core. This motion induces a magnetic field, which then induces a back-EMF in the wire. This causes a voltage drop in the circuit and increases the inductance in the core.The resistance component is caused by the electrons being forced to move through the core. This motion results in a drop in the current, as some of the energy is dissipated as heat. The resistance of the core is also affected by the stress it experiences, as the electrons tend to move more slowly when the core experiences stress.In summary, the SB28B0642 ferrite core is a small ferrite core that is widely used in communications, power, and networking applications. Its high permeability value makes it ideal for use in broadband communications applications. The working principle of the core involves electrons being forced to move through the core, causing a magnetic field to form. This magnetic field has both resistance and inductance components. By properly understanding and utilizing the characteristics of the ferrite core, it is possible to design and build circuits that are resistant to EMI, and thus provide better performance and reliability for the current electronic industry.
