Ferrite Bead

This brief article is intended for those who may be new to the field of compliance engineering and want a better understanding of process to design products that are immune to electrostatic discharge (ESD) events. 

For many applications, especially in digital designs, you can see decoupling networks composed of several different (big and small) capacitors in parallel. But, sometimes this technique can be dangerous.

The automotive industry and individual automobile manufacturers must meet a variety of EMC requirements.

Sometimes a ferrite is used to remove ringing in some applications as in power electronics or digital circuits.
