This plot is a close approximation to the real part of the impedance of a ferrite bead. The plot indicates that at low frequencies, the impedance is inductive (but has essentially no effect) and that it drops to virtually zero at a point that is beyond the plot. This is a reference plot where the axis scale is logarithmic, the frequency range is a little bit too narrow to show clearly the part before the bead impedance transitions to constant impedance, and the top plot is a log scale instead of linear.
So a “logical” thing to do with the impedance of a ferrite bead is to plot the real part against frequency, as shown below. Specifically, it rises and then falls logarithmically with frequency. The problem is that the impedance of the ferrite depends on frequency in such a way that it can only be approximated by other curves. The real part is an inductance, while the imaginary part is the frequency-dependent impedance. The time constant is essentially the time for a cycle of magnetic field for the magnetic field to pass through one diameter of the ferrite. The impedance has two parts a real and an imaginary part. $$Z_\text$ is the effective impedance and $\tau$ is the time constant of the bead.
The “frequency shaping” of a ferrite bead is mostly necessary because the impedance of the ferrite dramatically changes as a function of frequency.Ĭonsider this formula for the impedance of a ferrite bead: I just heard that they have different effect on the frequency filtering.įerrite has to be chosen as a function of impedance. Isn’t the shaper curve better for the frequency filtering? Why do people use ferrite beads with round or donut shape? If we are using ferrite beads for frequency filtering, Why do ferrite beads (round or donut shaped)? CloneDVD2 2.9.3.3 Final Keygen ((BETTER)).epub ➕
