The 2677540002 is a split round cable EMI suppression core manufactured by Fair-Rite Products designed to provide electromagnetic interference filtering for multi-strand cables and single conductors. This ferrite core features a polypropylene case that enables easy snap-together assembly, allowing for convenient installation in equipment where retrofit applications are required. The core is constructed from ferrite material optimized for common-mode filtering in round cables, with typical impedance values of 135 O at 25 MHz and 200 O at 100 MHz, delivering effective suppression across a broad frequency range. The core dimensions are 6.35±0.15 mm (A), 2.95±0.45 mm (B), and 25.4±0.75 mm (C), with a weight of 2.5 g and a coercivity of 0.91 Oe. These specifications make the 2677540002 suitable for applications requiring high-frequency EMI suppression in telecommunications, data transmission, and industrial control systems where cable-mounted filtering is essential.
