Inductors and Ferrites for Use in EMC

Magnetic materials used in inductors and filters have specific functions and purposes. However, knowing which to choose can be confusing.

Use of Ferrites in PCB Reference Planes

Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.

How Ferrites Are Specified for RF Performance

Ferrites are frequency dependent components used to attenuate unwanted high frequency RF signals that...
