    • A filter capacitor comprising a substrate of at least one layer of a low temperature co-fires ceramic (LTCC) tape supporting alternating active and ground electrode layers segregated by a dielectric layer is described. The substrate is preferably a laminate of three LTCC tapes pieces that are heated under pressure and at a relatively low temperature to become a laminate that maintains its shape and structure dimensions even after undergoing numerous sintering steps. Consequently, relatively thin active and ground electrode layers along with the intermediate dielectric layer can be laid down or deposited on the LTCC substrate by a screen-printing technique. A second laminate of LTCC tapes is positioned on top of the active/dielectric/ground layers to finish the capacitor. Consequently, a significant amount of space is saved in comparison to a comparably rated capacitor or, a capacitor of a higher rating can be provided in the same size as a conventional prior art capacitor.
    • 描述了一种滤波电容器,其包括至少一层由介电层隔离的交替的有源和接地电极层的低温共烧陶瓷(LTCC)带的衬底。 该基材优选是在压力下和相对低的温度下加热的三个LTCC带片的层压体,以成为即使在经历许多烧结步骤后也保持其形状和结构尺寸的层压体。 因此,可以通过丝网印刷技术将相对薄的有源和接地电极层与中间介电层一起铺设或沉积在LTCC基板上。 LTCC带的第二层压板位于有源/电介质/接地层的顶部,以完成电容器。 因此,与等效电容器相比,节省了大量的空间,或者可以提供与常规现有技术电容器相同尺寸的较高额定电容器。
