STEWARD, represented in Australia by RFI Industries , has released low-frequency LFB ferrite cores for EMI suppression. LFB ferrite material provides excellent impedance at lower frequencies. Optimum EMI attenuation is between 500KHz and 10MHz.
Parts are suitable for use in multiple turn configurations to multiply impedance. Each wire or cable turn can multiply impedance by four times.
A range of cylindrical ferrite cores are available in the material for cables and wiring harnesses that match industry standard cable sizes.
Custom sizes are also available on request. Typical applications include switching power supplies, automotive EMI filtering and ac/dc motor EMI.
