  • Patent number: 10332683
    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.

  • Patent number: 9445532
    Abstract: An improved capacitor packaging solution is presented that incorporates both thermal and electrical considerations. A package can include capacitor elements electrically coupled to a bus bar, and a thermally enhanced isolation layer between the bus bar and a case. The isolation layer can be provided adjacent a case base and sidewall portions. The bus bar can be disposed adjacent the isolation layer and be configured to extend along the package side and along the package length below the capacitor elements to provide an extended path for heat dissipation from the bus bar prior to its contact with capacitor elements. The enhanced isolation layer is configured to conduct heat away from the bus bar to the case to avoid the hotspot temperature of the capacitor. Reduced capacitor temperature allows use of smaller, cheaper capacitors, reducing inverter costs without compromising performance.
