    摘要： Disclosed herein is a laminated filter with improved stop band attenuation, which is adopted in devices using a radio frequency, such as communication systems and/or broadcasting systems. The laminated filter forms cross capacitive coupling as feeding lines of input lead and/or output lead are coupled to a resonator pattern, and enhances an attenuation characteristic of stop band. Also, the laminated filter is minimized if feeding lines of the input lead and output lead are aligned in different layers, and the positions of the attenuation poles are easily controlled by adjusting the feeding line length.

    摘要： A multilayered chip capacitor (MLCC) includes internal electrodes and external electrodes formed to be perpendicular to the internal electrodes, whereby parasitic capacitance is reduced, resulting in no parallel resonance frequency effects. In addition, the MLCC has a capacitor structure, which provides a first surface and a second surface formed in a stacking direction of the dielectric layers in the capacitor body as a top surface and a bottom surface. Hence, in the thin capacitors having the same size, the number of internal electrode layers is increased, thereby reducing the equivalent series resistant (ESR) and equivalent series inductance (ESL). Further, the printed circuit board (PCB) having an embedded MLCC is easily manufactured.

    摘要翻译： 多层片状电容器（MLCC）包括形成为垂直于内部电极的内部电极和外部电极，由此寄生电容减小，导致没有并联谐振频率效应。 此外，MLCC具有电容器结构，其提供在电容器主体中的电介质层的堆叠方向上形成的第一表面和第二表面作为顶表面和底表面。 因此，在具有相同尺寸的薄电容器中，内部电极层的数量增加，从而降低等效串联电阻（ESR）和等效串联电感（ESL）。 此外，具有嵌入式MLCC的印刷电路板（PCB）容易制造。
