BB ferrite series for EMI Suppression

sheets TDK offers a wide range of ferrite cores applied fort EMI Suppression. Depending on field of application TDK engineers offer high-tech and cost-effective solutions with various technical performance.

The special attention is drawn to ferrite beads (cores with holes, across which current conductive wire goes through. For example, at present moment, TDK manufactures ferrite beads (BB series) on the base of NiZn materials such as HF30, HF40, HF57, HF70 characterizing by a high value of impedance.

BB ferrite cores can be applied in:
  • Imaging devices, audio equipment, automotive electronics, telecommunication devices, office automation equipment, and digital interface various other cables.
  • Absorption EMI and penetrating noise
  • Preventing parasitic oscillation

Frequency characteristics of absolute impedance |Z| value and absolute permeability value are represented for BB ferrite beads (HF70 BB6.4х5х3.2) рассмотрены в статье "Ферритовые материалы TDK".
