Ferrite Beads Basic Operations and Key Parameters
- Author: Ahmed Alamin
To ensure proper operating conditions and communication integrity, multiple standards that restrict noise and radiation levels at both subsystem and intersystem levels have been developed by governmental and professional entities. To meet the standard requirements, designers are tasked with using proper techniques to ensure that noise levels are below the set boundaries. Ferrite beads are one of the many circuit-level passive components used to reduce the EMI noise that propagates within an electronic system. This paper highlights the fundamentals of ferrite beads and the key parameters that must be considered when using them in a design.
