Magnetic materials used in inductors and filters have specific functions and purposes. However, knowing which to choose can be confusing.
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.
Sometimes a ferrite is used to remove ringing in some applications as in power electronics or digital circuits.
The International Electrotechnical Commission has released the second edition of IEC 62317-13:2015 standard. IEC 62317-13:2015 applies to “Ferrite cores - Dimensions - Part 13: PQ-cores for use in power supply ... Read More...
In our ideal world, safety, quality and performance are paramount. However, the cost of the final component (which includes the ferrite) has in many cases, become the deciding factor. This article is written as an aide for the design engineer looking for alternative ferrite materials as a means to reduce cost.
