Surface mount beads and common-mode surface mount beads are available from Fair-Rite in
several sizes. Their rugged construction decreases dc resistance and increases current carrying
capacity compared with plated beads.
The Common-Mode surface mount bead provides a common path for the magnetic flux generated
by the current to the load and the return current from the load. The current compensation results in
zero magnetic flux in the core.
