Patent ID: 8536970

Claim:
A multilayered miniature coil component, comprising: a plurality of coil layers and a plurality of insulating layers, the plurality of coil layers and the plurality of insulating layers being alternatively overlapped on each other, wherein: each of the plurality of coil layers includes a plurality of coils and a plurality of wires, each of the plurality of coils has a first end and a second end, and a plurality of first conductive portions is disposed on each of the plurality of coil layers, at least one second conductive portion is disposed on at least one of the plurality of coil layers; each of the plurality of insulating layers has a plurality of conductive through holes disposed correspondingly to the first conductive portions and the second conductive portions; through the plurality of wires, the first conductive portions, the second conductive portions and the conductive through holes, the plurality of coils in each of the coil layers are composed as a circuit loop; the plurality of coil layers comprises a top coil layer and a bottom coil layer, wherein at least one of coils of the bottom coil layer turns clockwise inwardly and at least one of coils of the bottom coil layer turns counterclockwise inwardly, and at least one of coils of the top coil layer turns clockwise inwardly and at least one of coils of the top coil layer turns counterclockwise inwardly, wherein two of the coils on non-adjacent two coil layers are directly electrically connected to each other via at least one of the conductive through holes, and the conductive through hole is separated from all of the wires and coils on the same insulating layer with the conductive through hole in order to be electrically isolated from all of the wires and coils on the same insulating layer with the conductive through hole.
