Abstract

L'invention concerne un noyau d'inductance comprenant : - un corps magnétique (400) comprenant une surface exposée (406), et formant un chemin magnétique médian (401a, 401b), - un drain thermique (410) compris dans le corps magnétique (400), le drain thermique (410) est une lamelle présentant une épaisseur, ladite lamelle présente une première conductivité selon la direction de son épaisseur, une seconde conductivité perpendiculairement à la direction de son épaisseur, la première conductivité étant inférieure à la seconde conductivité, la direction selon l'épaisseur est perpendiculaire au chemin magnétique médian (401a, 401b) dans le volume volumique du corps magnétique (400), la lamelle étant disposée de manière à drainer de la chaleur vers la surface exposée (406).
