DLFL-0132-45D2

Common Mode Chokes (CMC) are a type of electromagnetic component used to block the flow of undesirable high frequency electrical noise while allowing the flow of desired signals. The DLFL-0132-45D2 CMC is particularly suited for applications utilizing high speed digital information transfer (HDI) between two connecting points. It is designed to protect against signal integrity losses caused by crosstalk, ground bounce, and other sources of EMI, maximizing data-over-coax and data-over-twisted pair communication.

The DLFL-0132-45D2 CMC is composed of ferrite cores, which are wound with a special high frequency response wire. The cores provide for the magnetic saturation between the windings, resulting in a high impedance path for common mode noise and signal coupling, and a lower impedance path for desired signals. The ferrite cores are also designed to provide a low DC resistance and high inductance, providing improved signal integrity and enhanced EMI protection. The combination of the wire and core design provides the DLFL-0132-45D2 CMC with high impedance values in the MHz range, up to hundreds of MHz making it ideal for high speed digital applications including HDI.

The DLFL-0132-45D2 CMC is designed for surface mount application. It can be used as a simple EMI filter in cable harnesses and in any application requiring differential mode and common mode noise suppression. The DLFL-0132-45D2 CMC works by suppressing the flow of common mode signals, which are noise, while allowing differential mode signals, which are desired signals, to pass. The DLFL-0132-45D2 CMC is designed to provide the desired signal transmission with minimal signal loss.

The DLFL-0132-45D2 CMC is designed with a ferrite core and insulated metalized wire. The ferrite core is designed to improve the overall performance of the CMC by providing high impedance in the presence of high frequency signals. The metalized wire is designed to provide enhanced electrical and thermal stability and is applied with a bonding process that results in low parasitic inductance. This allows the DLFL-0132-45D2 CMC to handle high frequency signals up to hundreds of MHz with minimal signal loss.

The DLFL-0132-45D2 CMC provides a reliable and cost effective solution for protection against EMI in high speed digital communication applications. Its combination of the ferrite‑core design and insulated metalized wire provide the DLFL-0132-45D2 CMC with the capability to handle high frequency signals up to hundreds of MHz without significant signal loss. As a result, it is an ideal CMC solution for applications associated with HDI data transfers.
