Ferrite beads are small, donut-shaped components made of a type of ceramic material called ferrite. They are used in electronic circuits to suppress high-frequency noise and EMI (electromagnetic interference). Ferrite beads work by absorbing high-frequency energy and converting it to heat, which is then dissipated through the bead’s body.
Ferrite beads are available in a variety of sizes, shapes, and materials, each with its own unique set of characteristics. When choosing a ferrite bead, it is important to consider the following factors:
