Ferrite cores, also known as ferrite toroids, are a type of magnetic material composed of iron oxide and one or more additional metallic elements. The most commonly used core material is ferrite, which is made of iron-oxide powder and hardened resin. RA28B1265 ferrite core is a high performance ferrite core with reasonable overall size. It has a broad range of applications and plays a vital role in many aspects.

Application field of RA28B1265

RA28B1265 ferrite core is mainly used in the fields of communications, industrial control, automotive, etc. It is widely used for various applications, such as high frequency transformer, coupling transformer, pulse transformer, data transmission and signal transmission. In data transmission applications, its ability to shield against external noise and reduce undesired data is a benefit; while in signal transmission, it can reduce interference when sending signals over long distances.

In the industrial control field, RA28B1265 ferrite core can be used to shield against electromagnetic interference (EMI) and radio frequency interference (RFI); it also helps to reduce the distortion of signals. In the automotive field, it can be used to reduce the noise generated by electric motors and other components.

Working Principle of RA28B1265

The working principle of RA28B1265 ferrite core is based on Lenz’s law: opposite poles attract and like poles repel. A ferrite core generates a magnetic field when a current passes through it. This magnetic field is created by the interaction of the electrons with the magnetic material. As electrons move through the ferrite core, they create a magnetic flux, which interacts with the surrounding material to generate a response. The response is usually either an attraction or repulsion depending on the poles of the magnet.

In data transmission applications, the ferrite core acts as an EMI shield, allowing the signal to pass through but blocking out any external noise. The same effect occurs in signal transmission applications, where the core reduces interference when sending signals over long distances. In industrial control applications, the core can also be used to reduce the distortion of signals.

In addition to its shielding capabilities, RA28B1265 ferrite core also provides a wide range of useful features. It has high resistivity, which means it can handle higher currents, and its unique shape enables it to fit easily into various devices. It also provides excellent electrical insulation and is resistant to thermal shock.
