Ferrite Beads are designed to suppress high frequency noise and spikes on signal and power lines, and also have the ability to absorb electrostatic pulses.

Ferrite Beads are used to absorb ultra-high frequency signals, such as some RF circuits, PLLs, oscillator circuits, and ultra-high frequency storage circuits (DDR SDRAM, RAMBUS, etc.), which need to be added to the power input part of Ferrite Beads.

The function of Ferrite Beads is 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 desired useful signal. To remove these unwanted signal energy, use Chip Ferrite Beads to act as high frequency resistors (attenuators).
