Abstract

A multilayer electronic component includes: a body including one or more ceramic layers or magnetic layers; an inductor part including coil portions disposed in the body to be perpendicular to a lower surface of the body; a plurality of internal electrodes disposed in the body to be perpendicular to the lower surface of the body; and an input terminal, an output terminal, and a ground terminal disposed on the lower surface of the body, wherein the body includes a capacitor part comprising at least one among the plurality of internal electrodes and at least one among the coil portions with at least one of the ceramic layers or magnetic layers interposed therebetween.

First claim

What is claimed is:

1. A multilayer electronic component comprising:
a body including one or more ceramic layers or magnetic layers;
an inductor part including coil portions disposed in the body to be perpendicular to a lower surface of the body;
a plurality of internal electrodes disposed in the body to be perpendicular to the lower surface of the body; and
an input terminal, an output terminal, and a ground terminal disposed on the lower surface of the body,
wherein the body includes a capacitor part comprising at least one among the plurality of internal electrodes and at least one among the coil portions with at least one of the ceramic layers or magnetic layers interposed therebetween.

2. The multilayer electronic component of claim 1 , wherein each of the plurality of internal electrodes has a respective lead exposed to the lower surface of the body.

3. The multilayer electronic component of claim 1 , wherein the plurality of internal electrodes form at least two internal electrode units, said at least two internal electrode units having different widths.

4. The multilayer electronic component of claim 1 , wherein the inductor part and the capacitor part are connected to each other in parallel.

5. The multilayer electronic component of claim 1 , wherein the coil portions are connected to each other through vias.

6. A multilayer electronic component comprising:
a body including one or more ceramic layers or magnetic layers;
an inductor part including first and second coil portions disposed in the body to be perpendicular to a lower surface of the body;
a capacitor part including first and second internal electrodes disposed in the body to be perpendicular to the lower surface of the body, the first and second internal electrodes each having respective leads exposed to the lower surface of the body; and
an input terminal, an output terminal, and a ground terminal disposed on the lower surface of the body,
wherein the capacitor part includes a first capacitor comprising the first internal electrode and the second coil portion and a second capacitor comprising the second internal electrode and the second coil portion.

7. The multilayer electronic component of claim 6 , wherein the first and second internal electrodes have different widths.

8. The multilayer electronic component of claim 6 , wherein the inductor part and the capacitor part are connected to each other in parallel.

9. The multilayer electronic component of claim 6 , wherein the first and second coil portions are connected to each other through vias.
