Problems solved by technology

In this case, the overall length or overall width of the coil assembly may increase due to the thickness of the outer electrodes
In addition, when the coil component is mounted on the mounting substrate, the external electrodes of the coil component may come into contact with another component disposed adjacently on the mounting substrate, so that an electrical short circuit may occur

[0081] Figure 7 is a diagram showing a coil assembly according to the second embodiment, corresponding to the figure 1 A cross-sectional view taken along line II' in .

[0082] refer to Figure 1 to Figure 6 with Figure 7 , in the coil component 2000 in one embodiment, the shapes of the plating preventing parts R1 and R2 and the lead parts 231 and 232 may be different from those of the coil component 1000 described in the first embodiment. Therefore, in one embodiment, only the shapes of the plating preventing portions R1 and R2 and the lead-out portions 231 and 232 that are different from the previous embodiments will be described. Descriptions of other elements may be the same as in the first embodiment.

[0083] Regarding the plating preventing portions R1 and R2 applied in one embodiment, one surface of the plating preventing portions R1 and R2 may extend to the inner walls of the slit portions S1 and S2 unlike the first embodiment. In addition, the lead-out parts 2...

Abstract

The invention provides a coil component. The coil component includes a body, a support substrate embedded in the body, a coil portion including first and second lead-out portions disposed on one surface of a support substrate and spaced apart from each other, slit portions formed along edge portions between both end surfaces of the body, opposing each other, and a first surface of the body, respectively, and exposing the first and second lead-out portions to internal surfaces of the slit portions, respectively, plating prevention portions embedded in the first and second lead-out portions, respectively, and having first surfaces exposed to the internal surfaces of the slit portions, respectively, and first and second external electrodes disposed on the first surface of the body, spaced apart from each other, extending to the internal surfaces of the slit portions, respectively, and connected to the first and second lead-out portions, respectively.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2019-0165359 filed on December 12, 2019 at the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a coil assembly. Background technique [0003] Inductors (coil components) are representative passive electronic components used in electronic devices along with resistors and capacitors. [0004] As electronic devices have been designed to have high performance and reduced size, the number of coil components used in the electronic devices has increased, and the size of the coil components has decreased. [0005] Generally, the external electrodes of the coil assembly may be disposed on each of two surfaces of the main body that are opposite to each other. In this case, the overall length or overall width of the coil assembly may increase due to the thickness of the ex...
