Ferrite cores are devices that are designed to prevent high frequency noise or EMI (electromagnetic interference). These ferrite cores are made to be placed within an electric circuit. Key characteristics are the filter type (differential, signal, or power), number of lines, max current rating, impedance and a specified frequency, and mounting type (free hanging, surface mount, or through-hole).
