High Frequency Noise Suppression in an Extensive Ferrite Design

Laird Technologies produces an extensive line of ferrite products for signal line and EMI filtering applications.  Products include ferrite cable cores, connector plates, unique common mode chokes, CAN-Bus chokes, high current thru hole and surface mount components, chip beads, surface mount inductors and toroid inductor cores.

Laird Technologies' nickel-zinc ferrite parts are used extensively in the suppression of electromagnetic interference.  Suppression of EMI has become a major concern in the transmission, reception, and processing of electronic signals and data.  Ferrite materials exhibit varying magnetic properties depending on the frequency at which they are excited.  In electronic applications, the relation of the magnetic loss to frequency is used to design the equivalent of band pass filters, attenuating high frequency interference where the material's losses are high, yet passing lower bands where data is carried.

By changing the composition of ferrite, it is possible to enhance attenuation in selected frequency ranges.  Laird Technologies offers a family of ferrites with varying compositions to allow the user to select the optimal type of the application, as well as cable core, SMT common mode, differential mode and other configurations.

Laird Technologies' wide band transformer and filter cores, and manganese-zinc and nickel-zinc ferrite toroids range in initial permeabilities from 16 to 10,000.  These products are used primarily in pulse transformers, isolation transformers, dataline and power filters, and ground fault interrupters.  Parts are available bare or coated.

Laird Technologies offers its customers unique product solutions, dedication to research and development and a seamless network of manufacturing and customer support facilities located all across the globe.
