Abstract: Filters, filter assemblies, and methods of forming filters are provided. For example, a filter includes a plurality of dielectric layers that are stacked in a Z-direction to form a substrate having a top, a bottom, and a perimeter, with an outer dielectric layer disposed at the top. The filter also includes a plurality of conductive layers, with an outer conductive layer formed over the outer dielectric layer, and a plurality of vias that are defined along the perimeter of the substrate and extend from the outer conductive layer to the bottom of the substrate. An assembly includes the filter attached to a device substrate. A method of forming the filter includes forming the dielectric and conductive layers, such as by forming an outer conductive layer over an outer dielectric layer; stacking the plurality of layers to form a substrate; and defining a plurality of vias along the substrate's perimeter.

Abstract: The present invention is directed to a multilayer ceramic capacitor that includes a plurality of active electrodes and at least one shield electrode that are each arranged within a monolithic body and parallel with a longitudinal direction. The capacitor may exhibit a first insertion loss value at a test frequency, which may be greater than about 2 GHz, in a first orientation relative to the mounting surface. The capacitor may exhibit a second insertion loss value at about the test frequency in a second orientation relative to the mounting surface and the capacitor is rotated 90 degrees or more about the longitudinal direction with respect to the first orientation. The longitudinal direction of the capacitor may be parallel with the mounting surface in each of the first and second orientations. The second insertion loss value may differ from the first insertion loss value by at least about 0.3 dB.

Abstract: A multilayer ceramic capacitor may include a monolithic body including a plurality of dielectric layers and a plurality of electrode regions. The plurality of electrode regions can include a dielectric region, an active electrode region, and a shield electrode region. The active electrode region may be located between the dielectric region and the shield electrode region in a Z-direction. The dielectric region may extend from the active electrode region to the top surface of the broadband multilayer ceramic capacitor. The capacitor may include a plurality of active electrodes arranged within the active electrode region and at least one shield electrode arranged within the shield electrode region. The dielectric region may be free of electrode layers that extend greater than 25% of a length of the capacitor. A ratio of a capacitor thickness to a thickness of the dielectric region may be less than about 20.

Abstract: The present invention is directed to a multilayer capacitor, a circuit board containing the multilayer capacitor, and an integrated circuit package containing the multilayer capacitor. A multilayer capacitor includes a body containing alternating dielectric layers and internal electrode layers that each include a first electrode and a second, co-planar electrode, the first electrode having a main body with at least one lead tab extending from each of a top edge and a bottom edge thereof. The capacitor also includes a first external terminal and a second external terminal that each wrap from a top surface, along an end surface, to a bottom surface. The first external terminal is electrically connected to the first electrode of the first internal electrode layers along its lead tab leading edges, and the second external terminal is electrically connected to the first electrode of the second internal electrode layers along its lead tab leading edges.

Abstract: A varistor array can include a monolithic body including a plurality of dielectric layers. A first varistor can be formed in the monolithic body. The first varistor can include a first external terminal on a first end of the monolithic body, a first plurality of electrodes connected with the first external terminal, a second external terminal on a second end of the monolithic body, and a second plurality of electrodes connected with the second external terminal. The second plurality of electrodes can be interleaved with the first plurality of electrodes and can overlap the first plurality of electrodes at an overlapping area that is insensitive to a relative misalignment between the first plurality of electrodes and the second plurality of electrodes when the misalignment is less than a threshold. A second varistor can be formed in the monolithic body that is distinct from the first varistor.

Abstract: A broadband multilayer ceramic capacitor may include a monolithic body including a plurality of dielectric layers stacked in the Z-direction, a first external terminal, and a second external terminal. A plurality of active electrodes, a bottom shield electrode, and a top shield electrode may be arranged within the monolithic body. The top shield electrode may be positioned between the active electrodes and a top surface of the capacitor and spaced apart from the top surface of the capacitor by a top-shield-to-top distance. A bottom shield electrode may be positioned between the active electrodes and the bottom surface of the capacitor and spaced apart from the bottom surface of the capacitor by a bottom-shield-to-bottom distance. A ratio of the top-shield-to-top distance to the bottom-shield-to-bottom distance may be between about 0.8 and about 1.2. The bottom-shield-to-bottom distance may range from about 8 microns to about 100 microns.
