The 2643023201 is a 43 Shield Bead EMI suppression component manufactured by Fair-Rite Products, designed to suppress electromagnetic interference in signal lines and power distribution networks. This ferrite bead features a burnished surface finish and is constructed from 43 material grade ferrite, offering guaranteed minimum impedance specifications across multiple frequency bands. The bead has a compact form factor with outer diameter of 2.85 mm, inner diameter of 1.65 mm, and length of 3.75 mm, with a weight of 0.06 g. It provides typical impedance values of 10.3 O at 10 MHz, 15 O at 25 MHz, 22 O at 100 MHz, and 30 O at 250 MHz, with a DC bias field of 1.8 Oe per ampere-turn. These beads are commonly used in high-speed digital circuits, telecommunications equipment, and consumer electronics to attenuate high-frequency noise and improve signal integrity.
