Magnetic component

A magnetic component comprising:

• a first core having a first inner surface;
• a second core disposed on the first core, the second core having a second inner surface, the second inner surface facing the first inner surface;
• an outer bobbin disposed between the first core and the second core, the outer bobbin having a hollow tube portion, a first bottom portion and a first top portion, the first bottom portion and the first top portion being located at opposite sides of the hollow tube portion, the hollow tube portion has a winding outlet, the winding outlet corresponding to an opening of a combination of the first core and the second core;
• a first winding wound around outer side of the hollow tube portion;
• an inner bobbin disposed in the hollow tube portion, the inner bobbin and the outer bobbin being not formed in one-piece structure, the inner bobbin having a second bottom portion and a second top portion, the first core and the second core fully covering the hollow tube portion and the inner bobbin, the second bottom portion extending towards the first bottom portion or the winding outlet, the second top portion extending towards the first top portion or the winding outlet;
• and
• a second winding wound around the inner bobbin, a winding end of the second winding extending laterally out of the winding outlet of the hollow tube portion, the outer bobbin, and the opening of the combination of the first core and the second core, the winding end of the second winding extending from between the second bottom portion and the second top portion, the first core and the second core through the winding outlet of the hollow tube portion and the opening of the combination of the first core and the second core;
• wherein the second bottom portion is exposed to bottom side of the first bottom portion, such that the first bottom portion overlaps the second bottom portion in a height direction of the magnetic component;
• the second top portion and the second bottom portion abut against inner side of the hollow tube portion.
