摘要： This disclosure describes methods and systems for minimizing electromagnetic interference (EMI) noise emanating from a ceramic capacitor. The ceramic capacitor may include several terminations are on a bottom portion of the capacitor. The capacitor may be designed to include several capacitors formed from electrode layers. The capacitor may include a conductive coating on an outer peripheral portion. The coating may include conductive materials such as Cu, Ni, Ag, and/or graphite. Alternatively, some regions of the capacitor may include electrode layers built into the capacitor that are not associated with capacitors. In this manner, the ceramic capacitor may be free of the conductive coating to locations proximate to the described electrode layers not associated with capacitors. The conductive coating can act as an electromagnetic shielding to prevent the EMI noise from emanating outside the electromagnetic shielding. Also, the conductive coating can be electrically grounded (e.g., to printed circuit board) via terminals.

摘要： Capacitor devices with electrodes that are geometrically arranged to reduce parasitic capacitances are described. The capacitors may be multilayer ceramic capacitor (MLCC) structures in which certain electrodes may have a clearance from a capacitor structure wall, such as top wall. In circuits and devices where that particular capacitor wall may be placed near a shielding structure, the clearance may reduce unintended parasitic capacitances between the shield structure and the electrodes. As a result, the shield structures may be placed closer to the electronic components, which may allow circuit boards and electronic devices with a lower profile.
