WebFerrite beads are good for high frequency applications because they don't suffer the capacitance effects that inductor coils will have. i.e. parasitic capacitance between the turns. But you don't choose a ferrite to have a certain inductance, you choose it to have a particular impedance at a particular frequency. e.g. 200 ohms at 200MHz. WebMay 16, 2024 · One of the major applications of ferrite beads is for EMI reduction in high-speed PCBs. At high frequencies, PCB traces behave like antennas. The use of ferrite beads can minimize EMI emissions and absorption through traces within a circuit board. Ferrite Cores Cables are susceptible to EMI noises.
