Ferrite Bead

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

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.

To protect the hearing health of hearing aid users, researchers in the relevant areas have been studying the effects of EMI on hearing aids.
