Abstract

The core contains ferrite granules (1 to 5) of at least two different sizes. The smaller granules (5) fill the intermediate spaces under the larger granules (1 to 4). The advantage is that a better filling factor, and hence better magnetic properties of the coil core, are achieved. <IMAGE>
