The 2643022401 is a 43 Shield Bead ferrite EMI suppression component manufactured by Fair-Rite Products for electromagnetic interference suppression applications. This bead features typical impedance values of 41 O at 10 MHz, 63 O at 25 MHz, 85 O at 100 MHz, and 93 O at 250 MHz, with a calculated DC bias field of 1.5 Oe for single-turn, single-ampere conditions. The bead has outer diameter (A) of 5.1 mm, inner diameter (B) of 1.45 mm, and length (C) of 6.35 mm, with a weight of 0.38 g, and the length dimension can be modified to suit specific applications. These suppression beads are controlled for guaranteed minimum impedance specifications and are commonly used in signal conditioning, noise filtering, and EMI mitigation in electronic devices and instrumentation systems.
