US 2015/0310991 A1 · MULTI-LAYERED CERAMIC CAPACITORS

Abstract

This application relates to multi-layered ceramic capacitors (MLCC) that can be surface mounted, include multiple terminals, and handle multiple voltages. The MLCC can include electrode and dielectric layers that are stacked in parallel to a printed circuit board (PCB) on which the MLCC can be attached. A set of primary conductive pads can be formed on the bottom of the MLCC in order to create a conductive interface between the PCB and the MLCC. Secondary conductive pads are formed on the side of the MLCC, and can extend perpendicular to the PCB. The secondary conductive pads are created by stacking internal electrode plates together and connecting them electrically and mechanically to each another. This arrangement provides for multiple voltages and electrical connections at the MLCC while reducing reverse piezoelectric and/or electro-striction noise.
