This application manual from Murata packs a lot of information about noises generated from most electronics equipment and what are the right filters to suppress these.

To make effective noise suppression in electronic equipment it is necessary for design engineers to have a good understanding of the various types of EMI suppression filters available and the characteristics so that they can use suitable components. Because filtering characteristics of EMI suppression filters depend significantly on the construction, a wide variety of products are available in the market, it is difficult to understand all of them.
This brochure provides an overview of EMI suppression filters by classifying them into several groups and describing the characteristics of each group along with a brief summary for the engineers.
This publication is intended to help readers to make correct selection of EMI suppression filters for their applications.
