Bead inductors dedicated to suppress high frequency noise and spikes interference signal lines, power lines, but also has the ability to absorb electrostatic pulses. Beads are used to absorb UHF signals, like some of the RF circuit, PLL, oscillator circuit, a memory circuit with ultra-high frequency (DDRSDRAM, RAMBUS, etc.) need to add beads in the power input section, and the inductor is an energy storage components used in the LC oscillator circuit, the low-frequency filter circuit, the application frequency range rarely exceeds 50MHZ. Beads have a high resistivity and magnetic permeability, in the equivalent series resistance and inductance, the resistance and inductance values with frequency.
