Multilayer ceramic capacitor structures may include structural arrangements, materials, and/or substrate modifications that can improve the reliability of the capacitor for long-term usage when faced with environmental stress. Embodiments may implement reduced entryways in the termination patterns of the capacitor to decrease damage potential due to exposure of moisture. Embodiments may implement structures that decrease interfaces with different physical characteristics, which may lead to a reduction in the formation of micro-fractures during regular usage. Methods of manufacture for the features that improve reliability are also detailed.

Reliable capacitor structures

Capacitor devices having multiple capacitors with similar nominal capacitances are described. The capacitors may be multilayer ceramic capacitors (MLCCs) and may be fabricated employing class 2 materials. The arrangement of the electrodes in the device may reduce relative variations between the capacitors of the device. The capacitor devices may be allow high performance and compact electrical circuits that may employ matched capacitors.
