Working Principle of Ferrite Beads | Zxcompo Electronics Co., Ltd
Ferrite beads are a passive component used in circuits. Their main function is to suppress high-frequency noise. Its working principle is based on the impedance properties of the ferrite material in the magnetic beads to AC current.

PB Series High Current Multilayer Chip Ferrite Beads
When a high-frequency current passes through a ferrite bead, the magnetic permeability of the ferrite material decreases as the frequency increases, causing the impedance of the ferrite bead to high-frequency signals to increase. This increase in impedance manifests itself as a combination of inductive (inductance) and resistive (resistance), effectively absorbing and suppressing high-frequency noise.

In addition, this impedance characteristic of ferrite beads also has a filtering effect on signals in the circuit, which can help reduce electromagnetic interference (EMI) and improve the signal integrity of the circuit. Therefore, ferrite beads are widely used in various electronic equipment, such as power lines, data lines, and communication lines, to suppress noise and improve system stability.
