Ferrite beads SMB, BDS

SM Beads (Surface Mounted Beads)

EMI bead cores are used to suppress or reduce a high frequency noise in electronic circuits, by utilitizing the characteristics of increasing the impedance in high frequency. Ferrite beads are often called ferrite bead cores, ferrite EMI filters.

Applications:

  • suppression of asymmetric and symmetric interference in the range of 100kHz - 1GHz
  • cards and PC hardware
  • industrial process control
