Common mode chokes are a type of noise suppression component that utilizes the principle of impedance transformation to reduce electromagnetic interference (EMI) in circuits. The ELF-18N032A is a common mode choke designed to provide EMI suppression solutions in a wide variety of applications, such as switching power supplies, high-speed serial data transmission, and automotive applications. It also provides EMI/RFI suppression for electronic systems.

The ELF-18N032A is designed with a high common mode impedance from a minimum frequency of 150MHz and a maximum frequency of 2.3GHz. This EMI filter is composed of a ferrite center core and multiple ceramic cores, as well as four high-precision copper windings for high stability and high accuracy. Its strong anti-interference performance effectively reduces the electromagnetic radiation generated by high-frequency circuits.

The ELF 18N032A is capable of eliminating common mode interference in high-frequency applications such as USB 3.0, HDMI, MIPI, LVDS, and FPD-Link. It is an ideal solution for preventing EMI interference problems in high-speed data transmission, automotive systems, industrial automation systems, and other sensitive high- frequency electronics. The high common-mode impedance and strong noise suppression capability of the ELF 18N032A make it an ideal choice for a wide range of sensitive high-speed applications.

The ELF 18N032A is a four-electrode device. It includes two common-mode chokes on each end of the ferrite core, one at each winding. Each of these two common-mode chokes is linked electrically and physically with a ceramic core connected to the fourth electrode. This fourth electrode connected to the ceramic core allows for higher frequency operation than other common mode chokes. It also has a dual-mode function; one mode uses all four electrodes, while the other mode bypasses one of the common modes to provide a higher inductance and overall higher performance in high-frequency noise suppression.

The ELF 18N032A is also designed for a direct connection to the ground terminal, which eliminates the need for extra shielding materials. This helps reduce the noise emission generated by the device. Its compact size and low profile allow for easy installation within a limited space. The ELF 18N032A is RoHS compliant and UL recognized and has a long service life.

In summary, the ELF-18N032A is a high-performance common mode choke designed for a variety of high-frequency applications. It offers high common mode impedance, noise suppression capability, dual-mode operation, direct grounding, compact size, low profile, long service life, and RoHS and UL recognition. It is an ideal solution for EMI suppression needs in high-speed data transmission, automotive, and industrial applications.
