The CBF series SMD EMI Suppression Ferrite Bead can be put directly on the printed circuit board. They offer excellent anti-EMI properties and low DC resistance. Placed very close next to the interference source even with smallest size 0402, maximal impedance at 1000R can be reached. The high speed SMD ferrites have lower impedance in the lower frequency ranges thus they have only a low attenuation for fast signals. The wide band SMD ferrites already show high impedance in low frequency range. Therefore they are wide band through the whole spectrum. The high frequency SMD ferrites have due to a modified internal layout an increased effective suppression frequency range. Consequently the impedance at 1GHz is up to 3 times higher. The high current SMD ferrites are available in all three types such as high speed, wide band and high frequency. It is suitable for control signals, RS232, RS422 and DC/DC converter.
