Common Mode Chokes are electromechanical devices that take advantage of the interaction between their windings to reduce the level of common-mode noise on a circuit. They are considered EMI filters, and so they are responsible for controlling and reducing the amount of electromagnetic interference that is picked up by ancillary components.

The DLP11SN281HL2L, is a common mode choke, specifically designed for rejecting currents in the signaling lines in digital communication applications. Generally speaking, cross-talk and common-mode emissions generated by the flow of data signals on the pairs of the twisted signal lines will be reduced or eliminated thanks to the use of this choke.

The working principle of the DLP11SN281HL2L is relatively simple. In order to provide the most optimal performance, it is important to ensure that the installation and connection of the choke within a system is done correctly. This choke works on the principle of a toroidal inductor, and it is connected to two or more signal lines. The toroidal winding around a ferromagnetic core serves to filter out the high frequency noises, and any others currents produced in the form of common-mode noise on the line, by creating a high inductive impedance to them.

The DLP11SN281HL2L is typically used to reduce EMI on telecommunications lines or video/RF cables. It is also used in mobile phone applications such as mobile backhaul networks, digital subscriber line (DSL) and Ethernet networks. Additionally, it can be employed in automotive applications to suppress electromagnetic interference generated in systems such as airbag controllers and electronic control units.

The DLP11SN281HL2L\'s application field and working principle are well-suited for combating common-mode noises. Its simple construction and affordability make it a viable solution for a wide range of applications.
