Using EMI filters to counter strong electromagnetic waves and unwanted electric currents induced in a circuit.

What is electromagnetic interference and what causes it? The main approaches to filtering out EMI and reducing its impact. How to evaluate EMI filters and what to know about designing them.

Compared to traditional common-mode choke solutions, Monolithic EMI filters provide significantly more RFI suppression in a substantially smaller package. A multitude of factors are conspiring to ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
