The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.

Solar Electronics founder Al Parker used to say about EMI testing, “There’s more than one way to skin a cat.” Here are a couple more.

Implementing a process of EMC compliance for a specific project is much more than simply ensuring that the design engineers follow a long list of “do’s and don’ts” in the form of EMC design rules. Following this process will reap benefits when EMC performance is evaluated at the end of the design process.

In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.

This article addresses the latest changes to the KS C 9814-1 (and CISPR 14-1) standard.
