Abstract

The disclosure relates to the coil electronic component which is the outer electrode parallel to the mounting surface and is arranged in one side of the body. In such coil electronic component, the leader connecting the outer electrode and coil has the shape in which the concatemer of the mushroom shape is repetitively arranged through the thickness direction of the body.

Description

technical field [0001] The invention relates to a coil electronic component, in particular to a chip inductor. Background technique [0002] Recently, along with miniaturization and multifunctionalization of electronic products, demands for miniaturization and thinning of chip inductor components are increasing. Chip-shaped power inductors are mainly used in power supply circuits such as DC / DC converters in portable devices, and their development direction is aimed at miniaturization, high current, and low DC resistance. [0003] At the same time, due to the reduction of the mounting area and the increase of the self-resonant frequency (SRF: Self Resonant Frequency), it is required to develop a chip inductor in which the external electrode is parallel to the mounting surface of the chip inductor and arranged on only one side. device. [0004] The invention of the following Patent Document 1 is an invention in which it is found that the magnetic flux generated when an exter...
