Product Overview
The Fair-Rite 2643006302 is a broadband EMI suppression bead designed for board components. It is part of Fair-Rite's extensive selection of ferrite EMI suppression beads, guaranteed with minimum impedance specifications. This bead is particularly effective for suppression applications and is suitable for designs requiring reliable EMI filtering. Preferred parts, like this one, are recommended for new designs due to shorter lead times and ready availability.

Note on Part Numbering: The last digit of the part number indicates the bead's finish: '1' for not burnished, '2' for burnished, and '4' for Parylene coated (minimum coating thickness 0.005 mm).
Note on Impedance: Minimum impedance values are specified for the '+' marked frequencies and are the listed typical impedance less 20%.
Note on DC Bias: The 'H (Oe)' column provides the calculated dc bias field for 1 turn and 1 ampere. The actual dc H field in an application is this value multiplied by the actual NI (ampere-turn) product. Refer to the application note "How to choose Ferrite Components for EMI Suppression" for details on the effect of dc bias on impedance.
Note on Customization: The 'C' dimension (bead length) can be modified for specific applications. Beads can be supplied with a Parylene coating upon request.
Note on Kits: The 'Shield Bead Kit' (part number 0199000019) includes a selection of these beads.
