0443164151 – FAIR-RITE PRODUCTS CORP

The FAIR-RITE 443164151 is a split ferrite core designed for broadband EMI suppression. Fabricated from Fair-Rite’s 43/44 material, this core exhibits a nominal impedance of 305Ω at 250MHz, optimized for attenuating noise within that frequency range. Its split, round geometry facilitates installation around existing cables or wire bundles without requiring disconnection. The core’s material composition provides a balance between permeability and saturation flux density, ensuring effective noise filtering while minimizing signal distortion. Insertion loss characteristics are dependent on cable impedance and number of turns through the core. The 43/44 material is a manganese zinc ferrite, characterized by relatively high permeability and moderate losses at higher frequencies, making it suitable for broadband applications where a balance between impedance and frequency response is required.
