Cable FerritesFerrites are materials that are commonly used in filters and EMI (electromagnetic interference) optimization in cables. Ferrites have magnetic properties that allow them to absorb electromagnetic energy and prevent it from interfering with the signals carried by the cable. They are often used in the form of beads or rings that can be attached to the cable at specific points to provide EMI protection. Ferrites are effective at blocking a wide range of frequencies and are relatively inexpensive, making them a popular choice for EMI optimization in cables.
