Ferrite cores, or ferrite cables, are cables and wiring that are built with ferrite material. This material is magnetic and used to reduce electrical noise or interference. The SB28B0071AB is a ferrite core which is widely used in a variety of applications. In this article, we will discuss its application fields and working principles.

Application Fields
The SB28B0071AB is mainly used for noise suppression in fixed applications such as power supply lines, audio lines, and data lines. It can be used for signals with frequencies up to 150 MHz.

It is used to suppress noise generated by power supply lines, and it can be used for both AC and DC power lines. It is suitable for suppressing power-supply noise in both digital and analog circuits. It is suitable for suppressing noise caused by switching operations in digital circuits.

It is also widely used for suppressing noise generated on audio lines. This noise can be produced by rectification circuits, power amplifiers, digital circuits and so on. This noise often manifests itself as interference or hum. It can reduce this noise and improve sound quality.

The SB28B0071AB is also used for suppressing noise generated by data lines. Data lines include USB cables, HDMI cables, antenna cables, Ethernet cables and others. It is especially useful for suppressing the common-mode noise generated by these cables. It can reduce interference caused by these data lines and improve signal quality.

Working Principle
The main working mechanism of the SB28B0071AB ferrite core can be explained in terms of magnetic and electrical phenomena. Firstly, the ferrite core is made up of a mixture of iron particles and other metals. This mixture forms a magnetic circuit.

When electrical current travels through the ferrite core, it creates a magnetic field. This magnetic field interacts with the ferrite particles to create a new field which is perpendicular to the original one. This new field acts as a barrier to the current, blocking the noise signals and suppressing interference.

In addition, the ferrite particles also absorb energy from the original electromagnetic field. This absorption of energy prevents the interference signals from reaching the desired destination. The absorbed energy is converted to very little heat, which dissipates quickly.

The SB28B0071AB ferrite core is also designed with an inductive design that further dampens the interference. This inductive design provides an additional layer of noise suppression, which ensures that the desired signals reach their destination unimpeded.

In summary, the SB28B0071AB ferrite core is a versatile tool designed for noise suppression in a variety of applications. Its application fields include suppressing noise on power supply lines, audio lines, and data lines. Its working principle can be explained in terms of magnetic and electrical phenomena, with an inductive design providing an additional layer of protection.
