Common Mode Chokes, often called EMC chokes, are electrical filters designed to reduce common-mode interference in mixed-mode cables. The ELF-23F008A is a Common Mode Choke of this type, providing single-target filtering and sorting of interference from digital lines and control loops. Highly effective at suppressing both differential and common-mode electrical noise, this part is used extensively in the aerospace, automotive, and electronics industries.

The ELF-23F008A Common Mode Choke features an X3 ferrite material, which is a mix of nickel-zinc and cobalt ferrites with exceptionally high resistance to common-mode electrical noise, even in high-frequency applications. It’s also capable of providing up to 70 dB of isolation at frequencies of up to 500 MHz, making it an effective solution for interference reduction for various high-speed applications. Additionally, it has an operating temperature range between -40˚C and +125˚C, and an inductance of 1.7µH.

The working principle of the ELF-23F008A Common Mode Choke is based on the idea of electromagnetic induction. In this case, the electric currents that flow in one direction generate an opposite flow in another direction. This happens when an alternating current induces a corresponding voltage in the inductor, which then takes the electrical pulse and splits it in the two directions. The ELF-23F008A is designed to absorb those opposite flows, which will effectively block noise produced by digital line and control loops.

Finally, the ELF-23F008A Common Mode Choke can be used in a variety of applications. It is highly effective in suppressing both differential and common-mode electrical noise in communication systems, including power line communications, access control systems, motion control systems, and other related systems. It also provides EMI/EMC protection in many wired systems where the data signals need to be transmitted at fast speeds and still stay stable. Moreover, the ELF-23F008A Common Mode Choke is also used in various consumer electronics applications, where it helps to reduce interference and noise caused by digital motors, LED controllers, and similar equipment.
