Ferrite Cores - Cables and WiringIn this article, we will examine the application field and working principle of the 28R1261-200. This type of ferrite core is applicable in cables and wiring used in many different applications.A ferrite core is a type of magnetic material with high permeability and low core loss. It is used to filter electromagnetic interference (EMI), reduce crosstalk and improve signal strength for various types of cables and wiring. The 28R1261-200 ferrite core is a specific type of core that provides excellent filtering and protection to signal cables and wiring.The 28R1261-200 can be used for applications such as data communications, audio/video, power lines, control circuits, and speech decoding. It can also be used in the body of cables and harnesses to reduce EMI generated by other components. The 28R1261-200 has a maximum operating temperature of 85°C and a working deviation from ambient temperature of -40°C to 105°C.To understand how a ferrite core works, you must first understand what an inductor is. An inductor is a device that stores energy in the form of a magnetic field. When a current passes through an inductor, a magnetic field is produced which opposes the current flow. This opposition is known as inductance and it is measured in henrys (H). The 28R1261-200 ferrite core has a low inductance of between 0.8mH and 2mH and a high permeability which provides good voltage and current regulation.When a ferrite core is used in cable and wiring applications, it helps to reduce the amount of EMI that the cable may encounter. The core works by absorbing electromagnetic radiation and converting it into a lower frequency signal. This helps to keep the noise interference down and allows the signal to remain strong and reliable.In addition to providing EMI filtering, the 28R1261-200 ferrite core can also help to reduce crosstalk between signals. Crosstalk is a phenomenon where signals are transferred from one wire to another due to electromagnetic coupling. By using a ferrite core, the wires can be separated greatly reducing the amount of crosstalk.When using the 28R1261-200 ferrite core for cables and wiring, it is important to remember to take proper precautions to ensure that it is installed correctly. If the core is not installed correctly, it can cause problems such as failure to meet specifications or even create interference.In summary, the 28R1261-200 ferrite core is a great way to reduce EMI, reduce crosstalk, and improve signal strength in cables and wiring. It is easy to install and can help to provide reliable and high quality signals for numerous applications.
