Ferrite cores are devices that are designed to prevent high frequency noise or EMI (electromagnetic interference). These ferrite cores are made to be placed on cables or wires. Some key characteristics are the type (flat or round), the design (clamp, clip, hinged, solid, or tubular), the inner and outer dimensions, the length, the mounting type (cable tie, chassis mount, or free-hanging), and the impedance at a specific frequency.
