The 2643300101 is a 43 Shield Bead ferrite EMI suppression component manufactured by Fair-Rite Products for signal filtering applications. This bead features typical impedance values of 93 O at 10 MHz, 140 O at 25 MHz, 201 O at 100 MHz, and 215 O at 250 MHz, providing effective electromagnetic interference suppression across a wide frequency range. The bead has outer diameter (A) of 7.6 mm, inner diameter (B) of 2.25 mm, and length (C) of 15.1 mm, with a weight of 2.1 g, and the length dimension can be modified to suit specific applications. The component is RoHS compliant and available in both burnished and non-burnished variants, with optional Parylene coating available upon request. This bead is commonly used in instrumentation, data acquisition systems, and high-frequency signal conditioning where reliable EMI suppression and guaranteed minimum impedance specifications are required.
