Still higher in frequency the self-capacitance of the inductor takes over and the capacitive reactance dominates. They are dissipated as heat rather than circulating elsewhere in the system. The fact that the high frequency signals can be dissipated as resistive losses means that they are not reflected back into the system where they may find other routes to radiated or conduct. The fact that resistive losses rise above a certain frequency makes these ferrite bead inductors ideal for applications such as EMI filtering. In turn this means that the resistive losses rise above frequencies of 10 to 100 MHz dependent upon the ferrite in question. However as the frequencies increase the eddy current losses rise. Ferrites have a high resistivity and therefore the inductor is able to pass signals up to relatively high frequencies (dependent upon the ferrite in use) with only the inductive reactance affecting the circuit and not the resistive eddy current induced losses. The ferrites have a high permeability and as a result they make excellent high density inductors.Īdditionally the ferrites are highly resistive like cores including iron where eddy currents flow causing losses to be incurred. At low frequencies ferrite bead inductors act as a normal inductor. Using ferrite as their basis, these inductors are simple to make using a bead, or low cost if they are bought.įerrite bead inductors form very effective filters for applications such as reducing electromagnetic interference because of the properties of the ferrite using within the inductor.įerrites provide an excellent core material for a bead inductor.
