Abstract: A multilayer ceramic capacitor includes a body including a dielectric layer and first and second internal electrodes stacked in a first direction and having first and second surfaces opposing each other in the first direction, third and fourth surfaces opposing each other in a second direction, and fifth and sixth surfaces opposing each other in a third direction, and first and second external electrodes disposed on the third and fourth surfaces of the body, respectively, and connected to the first and second internal electrodes, respectively. The first and second external electrodes each include a central portion disposed in a center of each of the third and fourth surfaces and an outer portion disposed outside the central portion. T1>T2>T3, in which T1 and T3 are maximum value and minimum value of a thickness of the central portion, respectively, and T2 is a maximum value of a thickness of the outer portion.

Abstract: An inductor includes a body including an internal coil having first and second end portions and an encapsulant encapsulating the internal coil and containing magnetic particles. First and second external electrodes are on external surfaces of the body and electrically connected to the internal coil. A first metal expansion portion encloses the first end portion while coming into direct contact with the first end portion of the internal coil, and may be between the body and the first external electrode. A second metal expansion portion encloses the second end portion while coming into direct contact with the second end portion of the internal coil, and may be between the body and the second external electrode.
