Abstract: An electromagnetic interference suppressor includes a plurality of ferrite layers arranged in stacked relation and defining a generally rectangular ferrite body. Each ferrite layer includes a laterally extending electrical conductor including an elongate portion and at least one enlarged width portion connected thereto. The enlarged width portion permits connection to an adjacent lateral conductor by one or more tubular vertical conductors which extend through respective via openings in a ferrite layer. The tubular vertical conductor and enlarged width portions permit high current carrying capability and permit greater manufacturing tolerance in the assembly of adjacent layers and in forming the tubular vertical conductors. An associated method is also disclosed.

Abstract: Incrementally adjustable multilayer monolithic capacitors having a set of base electrodes extending to and being coextensive with a first terminal end surface of the capacitor and a set of incremental electrodes extending to and being coextensive with a side surface of the capacitor. The base electrodes are electrically interconnected by a conductive metal coating on the first terminal end surface. Capacitance values of the resultant capacitor can be incrementally adjusted by electrically interconnecting or disconnecting one or more of the incremental electrodes either along the side surface to which they extend and are coextensive with or along the second terminal end surface of the capacitor.
