High current ferrite electromagnetic interference supressor and associated method

摘要

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.
