Ferrite cores are an important part of cables and wiring. As the name suggests, they are cores of ferrite material used to reduce electromagnetic interference and provide shielding. The SE28B1240 ferrite core is a common example of this. This article will explain the application field and working principle of this core.

Application Field of SE28B1240

The SE28B1240 ferrite core is mostly used in coaxial cables and other shielded cables. It is designed to be used at high frequency, up to 3GHz, with a wide operating temperature range. It is also designed to have a high impedance to reduce the amount of electrical noise that would otherwise be present. Due to its strong construction and high-current capacity, it is also suitable for use in Power over Ethernet (PoE) applications.

The SE28B1240 ferrite core is also suitable for use in high-power surge protectors and medical equipment. With a impedance of 5 Ohms, it has the capability to withstand high electrical currents and protect the device from electrical surges and thermal expansion. This makes it an ideal choice for use in surge protectors and medical equipment.

Working Principle of SE28B1240

The working principle of the SE28B1240 ferrite core is similar to other ferrite cores. It uses the magnetic field created by an electric current to reduce the amount of electromagnetic interference (EMI) present in a cable. This is done by converting the EMI into heat rather than allowing it to travel down the wire. This helps to prevent EMI from affecting the performance of the connected devices.

The SE28B1240 ferrite core is also designed to reduce electromagnetic radiation (EMR). This is done using a combination of magnetic fields and resistance. This helps to reduce the amount of EMR that is emitted by the connected devices, thus reducing potential health risks.

Conclusion

The SE28B1240 ferrite core is an important component in the construction of cables and wiring. It is designed to reduce the amount of EMI and EMR present in the cable, thus reducing both potential electrical and health risks. It is an important component for use in surge protectors and medical equipment, as well as other high-frequency applications. The working principle of the SE28B1240 ferrite core is similar to other ferrite cores. It uses the magnetic field created by an electric current to reduce the amount of EMI present in a cable.
