About Ferrite Beads
Kemet Ferrite Beads
Ferrite beads are a type of electronic component made of ferrite, a ceramic material containing iron oxide. They are cylindrical in shape with two terminals, and are used to prevent high frequency noise on signal lines. Ferrite beads act as inductors, which filter out the noise on the signal line by forming a small loop with it that has a self-resonant frequency. This helps reduce electrical interference and keeps signals clean. Ferrite beads are available in many different sizes and shapes, as well as in both unshielded and shielded configurations. They are also highly reliable and inexpensive, making them a popular choice for noise suppression in high-frequency circuit designs.
