ABSTRACT:
An improved inductive device has a U-shaped ferrite magnetic core with a base and a pair of parallel legs integrally extending from the opposite ends of the base. A straight ferrite magnetic core is disposed between the opposed core legs to define airgaps respectively between the ends of said straight core and the legs. A winding is disposed to surround the straight core. Each of the core legs is formed to have a generally flush surface over substantially the entire length thereof such that the portion of the flush surface is cooperative with the end of the straight core to define the airgap.
