Ferrite Cores - Cables and Wiring

The 28B0825-000 is a ferrite core manufactured by Pulse and is part of their Ferrite Core series. It is a non-magnetic core that is designed for use in power, signal and data cables. Its application fields and working principles are described below.

Application Fields

The 28B0825-000 ferrite core is mainly used to protect cable assemblies from radiation interference and C E M field induced losses. Novel electric products, such as motor vehicles, cellphones, computer peripheral products, etc., have built in electronic components emitting or receiving electromagnetic radiation, and they cause interference with adjacent cabled components. Pulse provides their Ferrite Core applications mainly for these scenarios. The application field of the 28B0825-000 ferrite core includes but is not limited to: The suppression and filtration of electric currents in signal transmission and power lines, as well as the shielding and suppression of electrostatic interference.

Working Principle

The 28B0825-000 ferrite core works on the principle of electromagnetic induction. Electromagnetic induction is a phenomenon that occurs when the change in a magnetic field induces an electric current in an adjacent conductor. This effect is known as Faraday’s Law of Induction. Pulse’s 28B0825-000 ferrite core utilizes this principle by wrapping the cable in question with multiple layers of conductive material containing multiple ferrite cores. The different ferrite cores, each of a different type, based on their configuration and composition, are able to absorb, attenuate, or shield electromagnetic radiation. This radiation, depending on their frequency, is also capable of inducing an electric current in the core, which is then dissipated or attenuated, protecting any conductors in the vicinity.

The 28B0825-000 ferrite core is made from a material possesses inherent ferromagnetic properties, and is also capable of dissipating heat, ensuring longevity and minimal interference from environmental factors. The core can easily fit a range of possible cable sizes, and can also be cut to fit the exact sizes required in a particular application. In all designs, the cores are designed to be used in a wiring path in a manner that will reduce inductive reactance to the lowest level.

Conclusion

The Pulse 28B0825-000 ferrite core is designed for use in signal, power, and data cables, and it is ideal for absorbing, attenuating or shielding electromagnetic radiation. Through multiple layers of conductive material and different types of ferrite cores, this ferrite core can reduce inductive reactance while also dissipating heat to ensure longevity and limit interference from environmental factors. In conclusion, Pulse’s 28B0825-000 ferrite core is a great choice for cable protection and interference suppression in a range of applications.
