Inhibition of signal lines dedicated to beads, the power line frequency noise and interference peak, also has the ability to absorb the static pulse. Bead is used to absorb the high frequency signal, as some RF circuits, PLL, oscillator circuits, including ultra-high frequency memory circuit (DDR SDRAM, RAMBUS, etc.) need to increase the power input part of the bead, while the inductor is a store to components used in the LC oscillator circuit, the low-frequency filter circuit, the application frequency range rarely exceeds 50MHZ.
