Inductance is mainly filter, oscillation, delay, notch, the image saying: "pass DC, block AC". The magnetic beads are mainly used to suppress electrical radiation interference, high-frequency noise and spike interference, and absorb ultra-high-frequency signals. They are often used in PCBs, DC/DC modules, high-frequency switches, switching audio amplifiers, data lines, power lines, and signal lines. Wait. So what is the difference between an inductor and a magnetic bead?

The frequency characteristics of the magnetic bead and the inductor are different. In the low frequency band, the inductance of the magnetic bead increases, the resistance of the winding inductance decreases, and the inductance of the magnetic bead works, which can be regarded as a low-loss, high-Q value. Inductor; at high frequency, the inductance of the magnetic bead becomes smaller and the resistance value becomes larger, resulting in an increase in the total impedance, which can be regarded as a high-frequency blocking device.
