An inductor and a power module are respectively provided. The inductor includes an insulating body and a conductive body. The insulating body has a top surface and a bottom surface. The conductive body includes two pin parts and a heat dissipation part. A portion of each of the pin parts is exposed outside the bottom surface. The portions of the two pin parts exposed outside the insulating body are configured to fix to a circuit board. The heat dissipation part is connected to the two pin parts, the heat dissipation part is exposed outside the top surface, and the heat dissipation part is configured to connect to an external heat dissipation member. When the inductor is fixed to the circuit board through the two pin parts exposed outside the bottom surface, the two pin parts and the bottom surface jointly define an accommodating space for accommodating a chip.

Inductor and power module

The large-current inductor includes a first core member having a first winding piece, a second winding piece, a first indentation, and a second indentation; a second core member having a third winding piece, a fourth winding piece, a third indentation, and a fourth indentation; a third core member attached and joined to first lateral sides of the first and second core members; and a fourth core member attached and joined to second lateral sides of the first and second core members. A first coil member winds around the first and third winding pieces, and has its ends embedded into the first and third indentations. A second coil member winds around the second and fourth winding pieces, and has its ends embedded into the second and fourth indentations. The inductor enhances efficiency of energy storage by mutual inductance, and limits large current flow by leakage inductance.
