Abstract
An inductor component includes a plurality of conductive elements, each formed as an individual patch of conductive material, with the conductive elements arranged in a vertical stack and tightly coupled to one another. Dielectric is disposed between more adjacent conductive elements, the dielectric has a permittivity and is sufficiently thin so as to provide a mutual inductance factor of at least one-half or greater between adjacent ones of the conductive elements. The dielectric is typically thinner than the adjacent conductors.
