Ferrite Cores - Cables and Wiring is an important category for various electrical and electronic products. The 28R0480-100 application field and working principle is a great example of the use of ferrite cores in this field.

The 28R0480-100 ferrite core is a two-piece type of ferrite core with a low profile of just 4 mm. It is made with a combination of Ni-Zn and Mn-Zn – both are low to medium permeability materials that offer excellent shielding, making them ideal for EMI/RFI shielding applications. This type of ferrite core is often used in applications such as power inductor cores, EMI/RFI filters, and EMI/RFI cable shielding.

The main working principle of the 28R0480-100 ferrite core is magnetic saturation. The core itself is divided into two parts: the primary winding and the secondary winding. The primary winding consists of wire wrapped around the core material. This winding acts as an inductor, generating an electromagnetic field when an AC current is applied. The secondary winding consists of several turns of wire which are wound around the core material in the opposite direction. This winding acts as a transformer, transforming the AC current applied to the primary winding into a lower voltage at the secondary winding.

Magnetic saturation refers to the process in which the two windings become magnetically saturated. This occurs when the opposing magnetic fields generated by the primary and secondary windings oppose each other, creating a magnetic field of their own that cancels out the other. This field causes an increase in the impedance of the 28R0480-100 ferrite core, resulting in an improvement in the filtering performance and shielding performance of the core.

The 28R0480-100 is a great choice for applications that require low-to-medium frequency signal/noise filtering, such as power inductor cores and EMI/RFI shielding. It can be used in a variety of applications that require the use of a ferrite core, such as power supply lines, data cables, and even audio/video cables. Its low profile makes it ideal for use in compact devices, as well as for cable and wire shielding.

In addition to its use in EMI/RFI filtering and shielding applications, the 28R0480-100 ferrite core is also used in other applications such as transformers, inductors, chokes, and other signal processing circuits. Its low profile and excellent shielding capabilities make it a great choice for use in these devices.

The 28R0480-100 is an excellent choice for a number of different uses. Its low profile makes it a great choice for use in compact devices and cables, while its magnetic saturation properties make it a great choice for EMI/RFI filtering and shielding applications. Its versatility makes it an invaluable tool for a variety of applications.
