Ferrite Chip Beads

What are Ferrite Chip Beads?

In the transmission system, noise is classified in two ways: one is differential mode noise and the other is common mode noise. Ferrite beads are used to clean differential mode noise generated from either the signal line or power line circuit.

How do Ferrite Chip Beads Work?

Chip beads are used to absorb high-frequency noise and transform it into heat, to filter out the unwanted signal (noise).  

Wire Wound vs. Multilayer

Laird Inductive components offer both Wire Wound and Multilayer type Ferrite chip beads. In addition, high retention Multilayer type chip beads demonstrate excellent performance under power loads, and wire wound types will be a superior option, covering wide bandwidth frequency problems.
