Spiral-shaped closed magnetic core and integrated micro-inductance comprising such a closed magnetic core

摘要

The core (1) has a set of parallel branches (4, 5) arranged in different parallel planes, where the core is in the form of a rectangular spiral comprising two ends (2) joined to one another by a closing segment (3). The parallel branches (4) are perpendicular to the parallel branches (5), where the branches have different thicknesses. Air-gaps having reduced dimensions are arranged in the branches.
