Inductance with a ferrite pot core and method to adjust the reluctance of the core.

摘要

1. Inductance comprising a magnetic circuit in the form of a casing constituted of the super-position of two ferrite half-shells (1, 2) with an airgap (4) in its central core (1", 2"), characterized in that at least one (2) of the two half-shells which are assembled and fixed by gluing or hooking, comprises near the airgap (4) a thin wall (5) which is perforated with one or more holes (7) to obtain the value of the reluctance of the magnetic circuit.
