The 2861002702 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 with high-frequency performance characteristics, controlled for AL value with a minimum of 80 nH. The core exhibits typical impedance of 45 O at 100 MHz and 64 O at 250 MHz, with dimensions of 7 mm (A) × 3.1 mm (B) × 4.2 mm (C) and a weight of 0.3 g. All cores are supplied burnished and are commonly employed in airbag designs to prevent accidental activation, as well as in various RF and EMI filtering applications requiring broadband performance.
