Effect of magnetic beads In the finished circuit board, we will see some of the wires or components of the pin on the set of small black magnetic ring, which is described in this article to the beads. Ferrite bead full name for the ferrite bead filter (there is a kind of wrong crystal alloy magnetic data of the magnetic beads), is an anti-jamming components, filter out high-frequency noise effect is remarkable.
 
Ferrite data is characterized by high-frequency loss is very large, with high permeability, so that the inductance between the coil windings in the case of high-frequency high-impedance capacitor when the most magnetic beads in the current through the period, iron Oxygen on the low-frequency current is almost no impedance, and the higher the frequency of the current will be a greater attenuation. For the suppression of electromagnetic interference with the ferrite, the most important performance parameters for the permeability μ and full magnetic flux density Bs. Its equivalent circuit is an inductor and a resistor in series, the value of the two components are proportional to the length of the magnetic beads. When the wire through the ferrite core, the composition of the inductive impedance is followed by the increase in frequency added. High-frequency current in which the heat issue.
