The 2643001601 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 8 O at 10 MHz, 16 O at 25 MHz, 28 O at 100 MHz, and 36 O at 250 MHz, with a calculated DC bias field of 1.6 Oe for single-turn, single-ampere conditions. The bead has outer diameter (A) of 3.55 mm, inner diameter (B) of 1.65 mm, and length (C) of 3.3 mm, with a weight of 0.09 g, and the length dimension can be modified to suit specific applications. This component is ideal for use in signal conditioning, power supply filtering, and high-frequency noise suppression in instrumentation, data acquisition, and communication systems where controlled impedance characteristics are required.
