Abstract
Circuito magnético de ferrita conformado en un recipiente constituido por superposición de dos semi-coquillas de ferrita, y provisto de un entrehierro en su núcleo central, caracterizado porque, al menos una de las dos semi-coquillas, que están acopladas e inmovilizadas por pegado o engrapado, comprende en la proximidad del entrehierro, una pared delgada, cuya perforación parcial y gradual aumenta gradualmente el valor de la reluctancia del circuito magnético a un valor predeterminado.
