MULTILAYER CHIP ELECTRONIC COMPONENT AND BOARD HAVING THE SAME

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 10-2014-0054598 filed on May 8, 2014, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

The present disclosure relates to a multilayer chip electronic component and a board having the same.

In accordance with rapid growth of the market for small portable terminals due to the emergence of smart phones or tablet personal computers (PCs), multifunctionalization, miniaturization, and thinning of portable terminals have been further intensified.

Among these, since wireless communications circuits have been modularized, they require decreases in volumes thereof, in addition to multiband correspondence.

Meanwhile, as processing performance of a central processing unit (CPU) of a base band part is improved, wireless modules or radio frequency (RF) analog circuits are driven at high frequency to be subjected to electromagnetic wave interference from peripheral circuits, such that communications disruption may easily occur.

Meanwhile, an LC filter, a multilayer chip electronic component, is mounted on printed circuit boards of various electronic products including display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs) and the like, computers, smartphones, mobile phones, and the like, to serve as an electronic component for suppressing noise.

In accordance with the miniaturization of portable terminals, demand for such LC filters to be reduced in size while having high efficiency have also been required.

In addition, along with the rapid development of mobile terminals such as tablet personal computers (PCs), ultra books, and the like, the miniaturization and high integration of microprocessors have been conducted.

Therefore, an area of a printed circuit board is decreased and correspondingly, a space for mounting the LC filter is limited, such that multilayer chip electronic components satisfying the limited mounting space have been continuously requested.

Further, since portable terminals are being used within higher frequency ranges than ever, LC filters having excellent efficiency in such high frequency regions are required.

The ceramic body 110 may be formed by stacking the plurality of dielectric layers, and a plurality of internal electrodes are separated from one another with each of the dielectric layers interposed therebetween in the ceramic body 110.

The dielectric layers 111 configuring the ceramic body 110 may be in a sintered state and be integrated with each other so that boundaries between adjacent dielectric layers are not readily apparent.

The dielectric layers 111 may be formed by sintering ceramic green sheets containing a ceramic powder, an organic solvent, and an organic binder. The ceramic powder may have a high k-material and examples thereof may include a barium titanate (BaTiO₃) based material, a strontium titanate (SrTiO₃) based material, and the like.

According to an exemplary embodiment of the present disclosure, the first and second internal electrodes 121 and 122 may be formed of a conductive paste containing a conductive metal.

The conductive metal may be nickel (Ni), copper (Cu) palladium (Pd), or an alloy thereof, but is not limited thereto.

The internal electrodes may be printed on the ceramic green sheets forming the dielectric layers using the conductive paste by a printing method such as a screen printing method or a gravure printing method.

As described above, since the multilayer chip electronic component according to an exemplary embodiment of the present disclosure is mounted to be horizontal in relation to a board and the mounting surface thereof is the second main surface 6 of the ceramic body 110, although not shown in the drawings, a marking portion having a different color capable of being visibly distinguished may be further formed on one outermost dielectric layer in order to determine a mounting direction.

Therefore, the external electrodes contacting first to third electrode pads on a board on which the multilayer chip electronic component is mounted, to be described below, maybe the first to third external electrodes 131 to 133.

In this case, the first external electrode 131 may function as a signal input terminal, the second external electrode 132 may function as a signal output terminal, and the third external electrode 133 may function as a ground terminal or an earth terminal.
