An inductor includes a hollow outer housing, an inner magnetic core, and a coil wound around the inner magnetic core. The outer housing includes two spaced sidewalls. The inner magnetic core and the coil are received in the outer housing, and a gap is defined between each of two ends of the inner magnetic core and one of the sidewalls of the outer housing in a length direction. Two wire ends of the coil extend out of the outer housing. The inner magnetic core is provided with at least one slot extending from an upper portion thereof through a lower portion thereof in a vertical direction perpendicular to the length direction, so that the inductor can, under low loading or small current, have a higher inductance to generate larger ripple rejection capability and to reduce the loss of a power module.
