The connection and difference between inductance and magnetic beads

1. The inductor is an energy storage component, and the magnetic beads are energy conversion (consumption) devices; [1]
2. Inductors are mostly used in power supply filter circuits, and magnetic beads are mostly used in signal loops for EMC countermeasures;
3. Magnetic beads are mainly used to suppress electromagnetic radiation interference, while inductors are used in this respect to focus on suppressing conducted interference. Both can be used to deal with EMC and EMI problems; two ways of EMI, namely: radiation and conduction, different The approach uses different suppression methods, the former using magnetic beads and the latter using inductance;
4, magnetic beads are used to absorb ultra-high frequency signals, like some RF circuits, PLL, oscillating circuits, including ultra-high frequency memory circuits (DDRSDRAM, RAMBUS, etc.) need to add magnetic beads in the power input part, and the inductance is a kind The energy storage component is used in an LC oscillating circuit, a low-frequency filter circuit, etc., and its application frequency range rarely exceeds 50 MHz;
5, the inductor is generally used for circuit matching and signal quality control, the general connection and power supply connection. Magnetic beads are used where analog ground and digital ground are combined. Magnetic beads are also used for signal lines
