The difference and connection between magnetic beads and inductors [Copy link]

Magnetic beads have high resistivity and permeability, which is equivalent to a resistor and an inductor in series, but the resistance and inductance values vary with the frequency. They have better high-frequency filtering characteristics than ordinary inductors, and are resistive at high frequencies, so they can maintain a high impedance in a fairly wide frequency range, thereby improving the FM filtering effect.
