ELK-U101FB

Common Mode Chokes, as their name implies, are devices that are designed to reduce or eliminate the common mode currents that are transmitted over a pair of data lines. The ELK-U101FB common mode choke is designed to provide a reliable EMI filter solution for applications that require a combination of good attenuation in the high common mode range together with a low common mode voltage drop.The working principle of the ELK-U101FB involves the application of a series of thin, parallel plates that are mounted in the core body of the filter, allowing the inductor to act as a common-mode choke. The parallel plates create an area of the filter that is “resonant”, meaning that it can effectively impede the flow of excess common-mode current. In addition to this, the parallel plates also act as a physical barrier between the two data lines, allowing the inductor to create a magnetic field around the two data lines, further suppressing any excess common-mode current.The ELK-U101FB also features a wide range of filter characteristics, allowing the user to customize the filter solution to their particular application requirements. For instance, it is possible to select the filter characteristics in terms of its attenuation frequency, attenuation slope, and the minimum common-mode voltage drop. The filter also offers a wide temperature range, allowing its use in a variety of environments.The ELK-U101FB common mode choke is suitable for use in a variety of applications, such as in Ethernet, Serial ATA, and Fibre Channel systems. In these types of systems, it is often necessary to reduce the interference between the two data paths in order to ensure reliable data transmission. It is also suitable for use in automotive applications, where a reliable EMI filter solution is required in order to reduce the radiation that is emitted by the device.In conclusion, the ELK-U101FB common mode choke provides a reliable EMI filter solution for a variety of applications. Its wide range of filter characteristics allows for a customized filter solution that can effectively reduce the interferences between the two data lines. The filter also offers a wide temperature range, allowing it to be used in a variety of environments.
