The Fair-Rite 2643803802 is a round, solid ferrite cable core designed for EMI suppression on cables. It is made from Fair-Rite's 43 material, a NiZn ferrite optimized for conducted EMI suppression from 20 MHz to 250 MHz. The core has an outer diameter of 61mm, an inner diameter of 35.55mm, and a length of 12.7mm, weighing 118g. It is a free-hanging, solid design suitable for snap-on or slip-on installation over cables up to approximately 35mm diameter.
Electrically, the core provides a minimum impedance of 108Ω at 100MHz, with typical impedance values of 34Ω at 10MHz, 53Ω at 25MHz, 91Ω at 100MHz, and 160Ω at 250MHz. The material has an initial permeability of 800, a flux density of 3500 Gauss at 10 Oe, and a Curie temperature greater than 130°C. The core is burnished to remove sharp edges.
This core is commonly used in power cables, data cables, and other applications requiring suppression of common-mode EMI. It is RoHS3 compliant and has an MSL of 1 (unlimited). Note that compliance status is unverified and should be confirmed with the manufacturer.
