Abstract
An embodiment of an apparatus includes first and second core regions, first and second conductors, and an isolation region. The first core region has a first permeability, and the first conductor is disposed in the first core region. The second core region has a second permeability, and the second conductor is disposed in the second core region. And the isolation region is disposed between the first and second core regions, and has a third permeability that is significantly different than the first and second permeabilities. For example, the first and second conductors may be windings of respective first and second inductors, and the isolation region, which may be attached to, or integral with, the first and second core regions, may reduce the amount of magnetic coupling between the inductors to a level that is negligible, such that the inductors may be used in applications that call for magnetically uncoupled inductors.
