Ferrite Cores - Cables and Wiring

Ferrite cores are widely used in the wiring and cables industry. They act as a shield and are designed to protect electrical components and cables from currents and interference. The SB28B2027AB ferrite core is a great example of a ferrite core that is used to protect electrical components and cables from high-frequency currents and interference. Here, we will discuss the application field and working principle of the SB28B2027AB ferrite core.

Application Field

The SB28B2027AB ferrite core is designed for application within the low frequencies power supply and signal transmission industry. It can be used to reduce EMI/RFI and power supply noise in both DC and AC power lines. This ferrite core can also be used to suppress high-frequency interference in data transmission cabling, such as Ethernet, USB, and HDMI.

Working Principle

The SB28B2027AB ferrite core is a type of toroidal inductor. It works by finding the current in the loop generated by the alternating field of the magnet. If the alternating electric field interacts with the ferrite core, a current gets induced which helps in suppressing the noise generated due to the alternating field. The core works by storing the energy in its magnetic field and then releasing it, thus, providing a complete shield to the cables and preventing any undesired noise.

When it comes to power lines, this ferrite core works effective due to its high-performance capacitors. It can filter out any common-mode noise, even the small ones, generated from both low and high frequencies components, thus, enhancing the efficiency of the power supply. Furthermore, a layer of insulation is also provided which prevents any electric shock and also acts as an effective shielding against any electrical leakage.

Conclusion

The SB28B2027AB ferrite core is designed for application within the low frequencies power supply and signal transmission industry. It can be used to reduce EMI/RFI and power supply noise in both DC and AC power lines. It also works effective due to its high-performance capacitors, providing a complete shield to the cables and preventing any undesired noise.
