Ferrite Cores - Cables and Wiring

A ferrite core is one of the most common passive components used in the world of cables and wiring. It is composed of a magnetic material, typically ferrite, and is used primarily to provide magnetic shielding or to reduce electromagnetic interference (EMI) when dealing with a long length of wiring. Sources of electrical interference, such as electrical motors, lighting, or even a passing car can create interference that is picked up by a long run of wire. A ferrite core helps minimize this type of interference.The AB4X2X4.5W is a common ferrite core, typically used in audio/visual (A/V) applications and is designed for enclosing audio/visual cables. It has a length of 4.5mm, a diameter of 4mm, and a total area index of 2. Thus, it provides a large amount of magnetic shielding while maintaining a low profile, making it ideal for applications where space is at a premium.The AB4x2x4.5W ferrite core works by providing a parallel magnetic field in the middle of a section of long cable. This parallel magnetic field reduces the amount of electromagnetic interference that passes through the cable. By coupling the ferrite core to the cable, a uniform magnetic field is created around the cable, preventing interference.The core also provides electromagnetic shielding. Shielding is accomplished by either absorbing or attenuating the electromagnetic radiation that is emitted from sources of interference such as computer monitors, TV sets, lights, motors, etc. A ferrite core reduces the amount of electromagnetic radiation entering a long run of wiring or cable, protecting it from outside sources of interference.In addition to its utility in A/V applications, the AB4X2X4.5W ferrite core is also used in the automotive industry, telecommunications, and for general industrial wiring applications. In automotive applications, ferrite cores are used to enhance the audio system in a car or reduce the amount of noise generated by wiring and electrical systems. In telecommunications applications, ferrite cores are used to reduce interference on phone lines or mobile electronics. Finally, in general industrial wiring applications, the core is used to create a magnetic shield around cables, reducing interference between two pieces of equipment.The AB4X2X4.5W is an ideal ferrite core choice for a variety of applications due to its size, low profile, and shielding capability. It is easy to install, and it provides a great deal of shielding and protection for long runs of wire. It is especially useful in applications where large amounts of interference are likely to be encountered, such as A/V cables or automotive wiring systems. It is also suitable for a range of industrial wiring applications, providing a great deal of magnetic shielding while still maintaining a low profile.
