EMI Suppression Beads (2673021801) Part Number: 2673021801 73 SHIELD BEAD Explanation of Part Numbers: Digits 1 & 2 = Product Class Digits 3 & 4 = Material Grade Last digit 1= Not Burnished 2 = Burnished The last digit of the Parylene coated part is a 4, which is available upon request. The minimum coating thickness beads is 0.005 mm (0.0002). Fair- Rite offers a broad selection of ferrite EMI suppression beads with guaranteed minimum impedance specifications. Our Shield Bead Kit (part number 0199000019) contains a selection of these beads. For any EMI suppression bead requirement not listed here, feel free to contact our customer service for availability and pricing. Catalog Drawing 3D Model The C dimension, the bead length, can be modified to suit specific applications. Weight: 1 (g) Dim mm mm tol nominal inch inch misc. A 5.1 0.25 0.201 _ B 1.45 +0.25 0.062 _ C 11.1 0.35 0.437 _ Chart Legend + Test frequency The columnH (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 How to choose Ferrite Components for EMI Suppression. Typical Impedance () 1 MHz 47 5 MHz 101 + 10 MHz 123 + 25 MHz 98 Electrical Properties H(Oe) 1.5 Suppression beads are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%. Single turn impedance tests for 73 and 43 material beads are performed on the E4990A Impedance Analyzer. The 61 material beads are tested on the E4991A / HP4291B Impedance Analyzer. Beads are tested with the shortest practical wire length.CSV Download Fair- Rite Products Corp.
