The 2643375002 is a 43 Shield Bead, a ferrite EMI suppression component manufactured by Fair-Rite Products for electromagnetic interference suppression in electronic applications. This bead features typical impedance values of 52 O at 10 MHz, 76 O at 25 MHz, 110 O at 100 MHz, and 131 O at 250 MHz, with a DC bias field of 0.6 Oe per ampere-turn. The component has outer diameter (A) of 9.5 mm, inner diameter (B) of 4.5 mm, and length (C) of 14.5 mm, with a weight of 3.1 g, and the length dimension can be modified to suit specific applications. The bead is available in both non-burnished and burnished finishes, with optional Parylene coating available upon request. These beads are commonly used in signal conditioning, noise suppression, and EMI filtering applications where guaranteed minimum impedance specifications are required.
