Abstract

Die Erfindung bezieht sich auf ein induktives Bauelement (1) mit einem Stabkern (2) und einem Wickelkörper (3), in den die Stabkernachse umschließende Stromwindungslagen (4) eingebettet sind.The invention relates to an inductive component (1) with a rod core (2) and a winding body (3) into which current winding layers (4) enclosing the rod core axis are embedded.

Um einer Erhitzung des induktiven Bauelements entgegenzuwirken, wird vorgeschlagen, daß die Breite der innersten Stromwindungslage kleiner als die Stabkernlänge ist und daß die Breite der Stromwindungslagen von innen nach außen zunimmt.

Figure 00000001
In order to counteract heating of the inductive component, it is proposed that the width of the innermost current winding layer is smaller than the rod core length and that the width of the current winding layers increases from the inside to the outside.
