摘要： 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.

摘要： A filter capacitor comprising a pre-sintered substrate supporting alternating active and ground electrode layers segregated by a dielectric layer is described. The substrate is of a ceramic material 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 by a screen-printing technique. Using a relatively thin over-glaze in comparison to a thick upper dielectric layer finishes 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. The pre-sintered ceramic substrate is used instead of conventional tape cast technology for the base dielectric.
