The 2861000102 is a multi-aperture ferrite core manufactured by Fair-Rite Products, designed for suppression applications, balun (balance-unbalance) transformers, and broadband transformer designs. This core features a 67 material grade (high-frequency material) with burnished finish, and is controlled for A value performance. The core exhibits typical impedance of 166 O at 100 MHz and 226 O at 250 MHz, with a minimum AL value of 300 nH, making it suitable for high-frequency signal processing. Dimensional specifications include an outer diameter of 13.3 mm × 13.4 mm with a height of 3.8 mm and weighs 3.5 grams. This core is commonly employed in airbag suppression circuits, RF filtering, and broadband impedance matching applications where reliable high-frequency performance is required.
