Abstract

Se describe un dispositivo inductivo (100) y un método para fabricar un dispositivo inductivo. El dispositivo inductivo comprende: un núcleo magnético (170) que forma un espacio (160), el núcleo magnético comprende una porción de núcleo exterior (102) y una porción de núcleo interior (218), el núcleo magnético forma una primera separación (190) entre una primera parte (191) de la porción de núcleo interior y una segunda parte (192) del núcleo magnético (170), la primera parte (191) de la porción de núcleo interior comprende una superficie interior (193) define un primer orificio pasante (194); un elemento de sellado (180) alojado al menos parcialmente en el primer orificio pasante, el elemento de sellado comprende una superficie exterior (181) forma un primer sello con la superficie interior (193) que define el primer orificio pasante (194), de manera tal que al menos una parte del primer orificio pasante se sella desde la primera separación (190); un devanado (111) se aloja en el espacio (160) del núcleo magnético, el devanado define una primera dirección axial; y un material curado (131) se proporciona en al menos una parte de la primera separación (190).
