Abstract

Die Erfindung betrifft einen Kern 1 für ein induktives passives Bauelement, insbesondere Drossel, zumindest bestehend aus zwei im Wesentlichen parallel zueinander angeordneten und jeweils aus mehreren magnetisierbaren Schenkelabschnitten 3 bestehenden Schenkeln 2, wobei die Schenkel 2 an ihren beiden Enden durch jeweils ein Joch 5 miteinander verbunden sind. Erfindungsgemäß ist ein aus Ferrit bestehender Abstandshalter 9 vorgesehen, der jeweils zwischen den in Längserstreckung der Schenkel 2 hintereinander platzierten Schenkelabschnitten 3 unter Ausbildung einer Klebefuge 8 verklebt ist, wobei die effektive Querschnittsfläche in Längserstreckung der Schenkel eines Abstandshalter 9 zwischen 0,1 bis 20% der Querschnittsfläche eines Schenkelabschnitts 3 in Längserstreckung der Schenkel entspricht.
