The 2867000302 is a 67-material multi-aperture ferrite core designed for suppression applications, balun (balance-unbalance) transformers, and broadband transformer designs. This burnished core features dimensions of 13.3 mm (A), 10.3 mm (B), 7.5 mm (C), 5.7 mm (E), and 3.8 mm (H) with specified tolerances, and weighs 2.6 grams. The 67 material grade is controlled for A1 value and impedance characteristics, with impedance measurements performed using a single turn through both apertures at various frequencies. This core is also employed in airbag designs to prevent accidental activation, making it suitable for both RF/microwave and safety-critical applications requiring reliable electromagnetic performance.
