THIN FILM-TYPE COIL COMPONENT AND METHOD OF FABRICATING THE SAME

摘要

There is provided a thin film-type coil component having a size equal to or less than 0806 and including a ceramic main body, external electrodes including a plurality of first external electrodes formed on one surface of the ceramic main body and a plurality of second external electrodes formed on the other surface facing one surface of the ceramic main body, and a coil unit including a plurality of coil layers stacked in the ceramic main body, thereby obtaining low direct current (DC) resistance.

主权项

1. A thin film-type coil component, comprising:
a main body; and external electrodes including a plurality of first external electrodes formed on one surface of the main body and a plurality of second external electrodes formed on the other surface facing one surface of the main body, the main body including: an upper substrate and a lower substrate; an insulating layer formed between the upper substrate and the lower substrate; and first to fourth coil layers disposed in the insulating layer and including first and second coils as a double coil, wherein the first and second coils are wound to be parallel to each other in the same direction on the same plane, and wherein one ends of the first and second coils are connected to the external electrodes, and the other ends of the first and second coils are respectively connected to first and second centers, and wherein one ends of the first coils of the first and third coil layers are connected to a portion of the first external electrodes, and the second coils of the first and third coil layers are connected to a remainder of the first external electrodes, wherein one ends of the first coils of the second and fourth coil layers are connected to a portion of the second external electrodes, and the second coils of the second and fourth coil layers are connected to a remainder of the second external electrodes.
