Part Type Information
Fair-Rite offers a broad selection of ferrite EMI suppression beads with guaranteed minimum impedance specifications.
-Beads with a '1' as the last digit of the part number are not burnished. Parts that are burnished to break the sharp edges
have a '2' as the last digit.
-Upon request beads can be supplied with a Parylene coating. The last digit of the Parylene coated part is a '4'. The minimum
coating thickness beads is 0.005 mm (.0002'').
-The column 'H (Oe)' gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The
actual dc H field in the application is this value of 'H' times the actual NI (ampere-turn) product. For the effect of the
dc bias on the impedance of the bead material, see figures 18-23 in the application note
www.fair-rite.com/newfair/pdf/CUP%20Paper.pdf document for 'How to choose Ferrite Components for EMI Suppression.
-Suppression beads are controlled for impedances only. The impedances listed are typical values. Minimum impedance values are
specified for the + marked frequencies. The minimum guaranteed impedance is the listed typical impedance less 20%.
-Single turn impedance tests for 73 and 43 material beads are performed on the 4193A Vector Impedance Analyzer. The 61 material
beads are tested on the 4191A RF Impedance Analyzer. Beads are tested with the shortest practical wire length.
-Preferred beads are the suggested choice for new designs. Samples are readily available and orders have typically shorter lead
times than other beads. For any EMI suppression bead requirement not listed here, feel free to contact our customer service for
availability and pricing.
-The 'C' dimension, the bead length, can be modified to suit specific applications.
-Our 'Shield Bead Kit' (part number 0199000019) contains a selection of these beads.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1= not burnished, 2 = burnished and
4 = Parylene coated.
