Würth Elektronik Extends its Series of Wire-wound Ferrites

Würth Elektronik now offers its WE-RFI inductors in sizes 0402 and 0603, which can be used as inductors for HF applications or as ferrites for interference suppression.

3-D Modeling and Characterization of Ferrite and Nanocrystalline Magnetic Cores for EMI Applications

This study examines the impact of complex magnetic permeability in 3-D simulations of toroidal ferrites and magnetic cores for EMC applications, revealing its importance and limitations at different frequencies.

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...
