摘要： An electromagnetic interference (EMI) filter capacitor assembly is provided for shielding and decoupling a conductive terminal pin or lead of the type used, for example, in an implantable medical device against passage of external interference signals. The EMI filter is constructed of relatively inexpensive ceramic chip capacitors which replace relatively expensive feedthrough capacitors as found in the prior art. The chip capacitors are mounted directly onto a hermetic feedthrough terminal in groups of two or more which vary in physical size, dielectric material and capacitance value so that they self-resonate at different frequencies. This "staggering" of resonant frequencies and direct installation at the hermetic terminal provides the EMI filter with sufficient broadband frequency attenuation. In one preferred form, multiple chip capacitor groupings are mounted onto a common base structure, with each capacitor grouping associated with a respective terminal pin. In another preferred form, a non-conductive substrate is provided with metalized circuit traces to better accommodate the mounting of the chip capacitors. Additionally, novel chip capacitor geometry/termination-metallization is provided which significantly reduces the internal inductance of the capacitor to improve its high frequency performance as an EMI filter. Such reduced inductance chip capacitor designs are readily adaptable to incorporate multiple electrically isolated active plate sets within a single monolithic casing.

摘要： An EMI filtered terminal assembly including at least one conductive terminal pin, a feedthrough capacitor, and a counter-bore associated with a passageway through the capacitor is described. Preferably, the feedthrough capacitor having counter-drilled or counter-bored holes on its top side is first bonded to a hermetic insulator. The counter-drilled or counter-bore holes in the capacitor provide greater volume for the electro-mechanical attachment between the capacitor and the terminal pin or lead wire, permitting robotic dispensing of, for example, thermal-setting conductive adhesive.

摘要： A discoidal feedthrough capacitor has its active electrode plates disposed within a dielectric body so that an edge of the active electrode plates is exposed at a surface of a through-hole for a conductive lead. The conductive lead is conductively coupled to the exposed edge of the electrode plates without an intervening conductive termination surface. Similarly, a ground electrode plate set of the feedthrough capacitor may have an edge exposed at the outer periphery of the capacitor for conductively coupling the exposed edge of the ground electrode plate to a conductive ferrule without an intervening conductive termination surface.

摘要： An EMI feedthrough filter terminal assembly includes a feedthrough filter capacitor having first and second sets of electrode plates, a passageway having a first termination surface conductively coupling the first set of electrode plates, and a second termination surface exteriorly coupling the second set of electrode plates. A conductive ferrule disposed adjacent to the capacitor includes a conductive pad of an oxide resistant biostable material on a surface thereof conductively coupled to the second termination surface. A conductive terminal pin extends through the passageway in conductive relation with the first set of electrode plates, and through the ferrule in non-conductive relation. An insulator is fixed to the ferrule for conductively isolating the terminal pin from the ferrule. A hermetic seal is disposed between the insulator and the ferrule. A second conductive pad may be conductively attached to the terminal pin and to the first termination surface independently of the lead wire.
