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.

Electromagnetic interference (EMI) has a reputation for being one the most difficult aspects in power-supply designs. I think that this reputation comes, in large part, from the fact that most ...

Learn more about EMI filtering in rugged, high-density systems with this step-by-step guide to component selection and system ...

Differential-mode EMI currents flow only in the functional unit's active input and return path, and are isolated from the system ground or earth-return path. By understanding where EMI conduction ...

When electronic devices receive strong electromagnetic waves, unwanted electric currents can be induced in the circuit, interfering with intended operations. EMI filters deliver superior EMI ...
