Coupled inductor

A coupled inductor, comprising:

• a body;
• a first conductive wire;
• a second conductive wire, wherein at least one portion of the first conductive wire and at least one portion of the second conductive wire are disposed inside the body;
• a first electrode, a second electrode, a third electrode, and a fourth electrode disposed on a first surface of the body, wherein the first electrode and the second electrode are electrically connected to the first conductive wire, and the third electrode and the fourth electrode are electrically connected to the second conductive wire, and wherein a first horizontal line segment passing through the first electrode and the second electrode and a second horizontal line segment passing through the third electrode and the fourth electrode cross each other at a location inside a periphery of the first surface of the body;
• and
• an insulating layer disposed on each of the first conductive wire and the second conductive wire, wherein the at least one portion of the first conductive wire and the at least one portion of the second conductive wire are stacked together with the insulating layer along a vertical direction and wherein the insulating layer interfaces each of the at least one portion of the first conductive wire and the at least one portion of the second conductive wire.
