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