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.
