ABSTRACT:
The process provides practical manufacture of a two-piece, dielectric filled, ferrite toroid assembly while providing optimum electromagnetic characteristics presently not consistently available by manufacturing the toroid in a pressed one-piece configuration. A pair of complementary ferrite blanks of selected shapes are machined to dimension, and the mating surfaces thereof are selectively lapped. The complementary ferrite parts are then permanently assembled about a pre-machined dielectric insert, and the composite toroid is secured together by a selected adhesive selectively disposed therein.
