Cost-Effective Ferrite Cable Cores with Unmatched Performance

Laird Technologies’ extensive line of ferrite products for inductive and EMI filtering applications includes ferrite cable cores.

Our cylindrical EMI suppression ferrites provide a cost-effective means to reduce common and differential mode EMI.  These ferrite cable cores are most frequently used to suppress common mode EMI on the internal and external cable assemblies of electronic equipment.  By decreasing the levels of EMI radiated by internal cables, ferrite cable cores can reduce the cost and amount of overall shielding required to confine EMI within a product's enclosure.  They can also be used successfully on power cables that carry digital or analog signaling.

To achieve maximum EMI filtering performance in a given application, select a ferrite with an inner diameter most closely matching the outer diameter of the wire or wire bundle to be filtered.  The in-circuit impedance may be substantially increased by passing two turns of the wire conductor through the ferrite cable core.  A typical common mode application might have two conductors passed through a ferrite cable core.  With equal and opposite currents flowing through the core, zero net bias is established through the component and, thus, maximum impedance is realized from the ferrite.

Laird Technologies’ ribbon and flex cable EMI suppression ferrite cores provide a cost-effective means of reducing common mode EMI on flat or ribbon type cable assemblies.  They are most frequently used to suppress EMI on the internal data cable assemblies of electronic equipment.

Laird Technologies includes a selection of “split” components for retrofit and post-assembly operations.  Similar in performance to the one-piece core designs, these split ferrite cable cores provide excellent differential and common mode EMI suppression on both flat and round cable assemblies.  Lightweight, inexpensive metal or plastic end-clips provide secure closure of the ferrite onto the cable.

Contact Laird Technologies today for your complete ferrite cable core application solutions.
