摘要： Both discrete and array RC components are described using cofireable resistive material as part of internal electrodes of the device. The devices include a sintered body of multilayer ceramic material in which multiple first and second electrode layers are stacked. Each of the first layers comprises at least one resistive electrode pattern extending across the sintered body between respective pairs of terminations. The second layers comprise an electrode pattern extending transverse to the resistive electrode pattern, such as between end terminations. In some embodiments, opposing side electrodes serve as input and output terminals of a respective feedthrough filter. In a feedthrough arrangement, the third terminal may be provided by one or both of the end terminals. The invention also describes an improved termination structure including a layer made from a metal oxide material.

摘要： Methodologies and structures are disclosed for providing multilayer electronic devices having low inductance and high ratings, such as for capacitor devices for uses involving faster pulsing and higher currents. Plural layer devices are constructed for relatively lowered inductance by relatively altering typical orientation of capacitors such that their electrodes are placed into a vertical position relative to an associated circuit board. Optionally, individual leads may be formed so that the resulting structure can be used as an array. Internal electrodes may be arranged for reducing current loops for associated circuits on a circuit board, to correspondingly reduce the associated inductance of the circuit board mounted device. Leads associated with such devices may have added tab-like structures which serve to more precisely place the lead, to improve the lead to capacitor strength, and to promote lower resistance and inductance. Disclosed designs for reducing associated inductance may be practiced in conjunction with various electric devices, including capacitors, resistors, inductors, or varistors.

摘要： A multilayer electronic component includes a plurality of dielectric layers interleaved with a plurality of internal electrode elements and a plurality of internal anchor tabs. Portions of the internal electrode elements and anchor tabs are exposed along the periphery of the electronic component in one or more aligned columns. Each exposed portion is within a predetermined distance from other exposed portions in a given column such that bridged terminations may be formed by depositing one or more plated termination materials over selected of the respectively aligned columns. Internal anchor tabs may be provided and exposed in prearranged relationships with other exposed conductive portions to help nucleate metallized plating material along the periphery of a device. External anchor tabs or lands may be provided to form terminations that extend to top and/or bottom surfaces of the device. Selected of the conductive elements may be formed by a finite volume percentage of ceramic material for enhanced durability, and external lands may be thicker than internal conductive elements and/or may also be embedded in top and/or bottom component surfaces. A variety of potential internal electrode configurations are possible including ones configured for orientation-insensitive component mounting and for high density peripheral termination interdigitated capacitors.

摘要： Surface mount components and related methods of manufacture involve one or more thin film circuits provided between first and second insulating substrates. The thin film circuits may include one or more passive components, including resistors, capacitors, inductors, arrays of one or more passive components, networks or filters of multiple passive components. Such thin film circuit(s) can be sandwiched between first and second insulating substrates with internal conductive pads being exposed between the substrates on end and/or side surfaces of the surface mount component. The exposed conductive pads are then electrically connected to external terminations. The external terminations may include a variety of different materials, including at least one layer of conductive polymer and may be formed as termination stripes, end caps or the like. Optional shield layers may also be provided on top and/or bottom device surfaces to protect the surface mount components from signal interference. For embodiments where one or more thin film circuits are provided between insulating base and cover substrates, such thin film circuit(s) can be formed with conductive pads that extend to and are initially exposed along one or more surfaces of the resultant component. The cover substrate is formed with a plurality of conductive elements (e.g., internal active electrodes, internal anchor electrodes and/or external anchor electrodes) that are designed to generally align with the conductive pads formed on the base substrate such that conductive element portions are exposed in groups along one or more peripheral surfaces of a device. External plated terminations are then formed directly to the exposed portions of the conductive elements.

摘要： Low inductance capacitors include electrodes that are arranged among dielectric layers and oriented such that the electrodes are substantially perpendicular to a mounting surface. Vertical electrodes are exposed along a device periphery to determine where termination lands are formed, defining a narrow and controlled spacing between the lands that is intended to reduce the current loop area, thus reducing the component inductance. Further reduction in current loop area and thus component equivalent series inductance (ESL) may be provided by interdigitated terminations. Terminations may be formed by various electroless plating techniques, and may be directly soldered to circuit board pads. Terminations may also be located on “ends” of the capacitors to enable electrical testing or to control solder fillet size and shape. Two-terminal devices may be formed as well as devices with multiple terminations on a given bottom (mounting) surface of the device. Terminations may also be formed on the top surface (opposite a designated mounting surface) and may be a mirror image, reverse-mirror image, or different shape relative to the bottom surface.
