The 2843001502 is a 43-material multi-aperture ferrite core engineered for suppression applications across broadband frequencies from 20 to 300 MHz. This burnished core features typical impedance values of 59 O at 25 MHz and 88 O at 100 MHz, with mechanical dimensions of 13.30 mm (A) × 6.60 mm (B) × 7.50 mm (C) and a weight of 1.700 g. The 43 material exhibits an initial permeability of 800 at B < 10 gauss, a Curie temperature exceeding 130°C, and a temperature coefficient of initial permeability of 1.25 %/°C over the 20–70°C range. Multi-aperture cores are widely used in EMI suppression, balun transformers, and broadband transformer applications, as well as in airbag designs to prevent accidental activation. This preferred part is readily available with shorter lead times, making it an ideal choice for new designs requiring reliable conducted EMI suppression.
