摘要： The present invention relates to the inductors, for example, flat ribbon inductors and methods of forming thereof. An aspect of the disclosure provides an inductor comprising: a helical conductor a core having a core magnetic reluctance, the core comprising: a first core portion; a second core portion; and, a gap disposed between the first core portion and the second core portion and enclosed by the helical conductor, wherein the gap is configured to provide a gap magnetic reluctance wherein the gap magnetic reluctance is greater than the core magnetic reluctance; wherein the helical conductor has: a first region of the conductor which encloses part of the core, wherein the first region comprises a first pitch; and, a second region of the conductor which encloses the gap wherein the second region comprises a second pitch, wherein the second pitch is greater than the first pitch; wherein, in use, the second region of the conductor is configured to reduce a magnitude of interaction between the second region of the conductor and an electromagnetic field generated around the gap.
