Resonance Ferrite Beads are specially used to suppress high-frequency noise and spike interference on signal lines and power lines, and also have the ability to absorb electrostatic pulses. Magnetic beads are used to absorb ultra-high frequency signals. For example, some RF circuits, PLLs, oscillator circuits, and ultra-high frequency memory circuits (DDR SDRAM, RAMBUS, etc.) need to add magnetic beads to the power input part, and inductance is a kind of storage Energy components, used in LC oscillator circuits, medium and low frequency filter circuits, etc., whose application frequency range rarely exceeds 50MHZ. Magnetic beads have high resistivity and permeability, which is equivalent to a series connection of resistance and inductance, but the resistance value and inductance value change with frequency.
The function of the Resonance Ferrite Beads magnetic beads is mainly to eliminate the RF noise existing in the transmission line structure (circuit). The RF energy is the AC sine wave component superimposed on the DC transmission level, and the DC component is the required useful signal. To eliminate these unwanted signal energy, chip magnetic beads are used to play the role of high-frequency resistance (attenuator).
Resonance Ferrite Beads magnetic beads have high resistivity and permeability. It is equivalent to a series connection of resistance and inductance, but the resistance value and inductance value change with frequency. It has better high-frequency filtering characteristics than ordinary inductors, and shows resistance at high frequencies, so it can maintain a higher impedance in a relatively wide frequency range, thereby improving the FM filtering effect.
As a power supply filter, an inductor can be used. The circuit symbol of the magnetic bead is the inductance, but it can be seen from the model that the magnetic bead is used. In terms of circuit function, the principle of the magnetic beads and the inductor are the same, but the frequency characteristics are different.
