Abstract
Laminated components of the open magnetic circuit type including, or incorporating, inductors of the same type are manufactured by alternately superposing a plurality of green magnetic layers and a plurality of fragmentary, green conductor strips, each strip constituting about half a turn of coil in coil-forming conductor patterns, in such a manner that the ends of the conductor strips overlap the ends of adjacent strips whereas the remainders of the adjacent strips are separated by each interposing magnetic layer, the conductor strips being arranged so that they are vertically superposed along the same spiraling loci, sintering the resulting laminate to a solid sintered body, and, before or after the sintering, sectioning the laminate along the spiraling loci into individual components.
Claims9
Laminated components of the open magnetic circuit type including, or incorporating, inductors of the same type, each of which comprises a plurality of magnetic layers and a plurality of fragmentary conductor strips formed along the outermost edges of the magnetic layers to constitute about half a turn of coil each, said conductor strips being joined between and across the magnetic layers to form altogether a spiral coil-forming conductor pattern in which the strips are vertically superposed and connected on the same spiraling loci, the outermost peripheries of the conductor pattern being exposed from between the magnetic layers to the outside.
An open magnetic circuit type, laminated component comprises:
- a plurality of magnetic layers;
- a plurality of conductor strips, said strips being interconnected thereby defining a coil, said layers being interposed between said strips, each said strip being placed at an outermost edge portion of said layers.
