Abstract: 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.
