Abstract:
An encapsulated filtered feedthrough assembly for an implantable medical device including a ferrule, an electrical insulator coupled to the ferrule, a printed circuit board (PCB), a feedthrough conductor extending through the electrical insulator and the PCB, and a capacitor coupled to the PCB. The encapsulated filtered feedthrough assembly can include a mold defining an opening and located with respect to the printed circuit board such that at least a portion of the capacitor is positioned within the opening. A first non-conductive material can underfill the capacitor and a second non-conductive material can be backfilled into the mold to encapsulate the capacitor.
Abstract:
A capacitor includes a first terminal lead (500) for connecting a positive potential, a second terminal lead (502) for connecting a negative potential; a dielectric (501 ) arranged between a positive electrode (504) connected to the first terminal lead (500) and a negative electrode (505) connected to the second terminal lead (502), and a third terminal lead (503) connected to the second terminal lead (502) and further extending along the first terminal lead (500) and being insulated from the first terminal lead (500).
Abstract:
The described embodiments relate generally to a capacitor assembly for mounting on a printed circuit board (PCB) and more specifically to designs for mechanically isolating the capacitor assembly from the PCB to reduce an acoustic noise produced when the capacitor imparts a piezoelectric force on the PCB. Termination elements in the capacitor assembly, including a porous conductive layer in the capacitor assembly may reduce an amount of vibrational energy transferred from the capacitor to the PCB. Termination elements including a soft contact layer may also reduce the amount of vibrational energy transferred to the PCB. Further, capacitor assemblies having thickened dielectric material may reduce the amount of vibrational energy transferred to the PCB.
Abstract:
A feedthrough assembly may include a ferrule defining a ferrule opening, a feedthrough at least partially disposed within the ferrule opening and attached to the ferrule, and a plurality of chip capacitors. In some examples, the feedthrough may include a plurality of feedthrough conductive pathways extending between an externally-facing side of the feedthrough and an internally-facing side of the feedthrough. In some examples, respective ones of the plurality of chip capacitors are electrically connected to respective ones of the plurality of feedthrough conductive pathways and electrically connected to the ferrule.
Abstract:
Ein Durchführungskondensator (400) weist einen elektrisch isolierenden Körper (100) mit einer Durchgangsöffnung (110) auf, wobei eine Wand der Durchgangsöffnung des Körpers eine innere Metallisierung aufweist. Der Körper (100) weist außerdem eine äußere Metallisierung auf. Weiter ist ein elektrisch leitfähiges Zwischenglied (200) vorgesehen, das elektrisch leitfähig mit einem elektrischen Leiter (300) verbindbar ist. Das Zwischenglied (200) ist in der Durchgangsöffnung des Körpers (100) elektrisch leitfähig mit der inneren Metallisierung verbindbar.
Abstract:
A capacitor assembly for use in, and a method of assembling, a filtered feedthrough. The capacitor includes an insulative member fixedly attached to its bottom portion to inhibit high voltage arcing. The termination material present on the inner and outer diameters of the capacitor is absent from a portion of the capacitor proximate the bottom portion, e.g., at the insulative member.
Abstract:
A capacitive element for an implantable medical device feedthrough element includes a bore, to receive a feedthrough member, or pin of the filtered feedthrough element, an external surface extending laterally outward from a first opening of the bore, and a recessed area formed in the external surface and extending about an outer perimeter thereof. The recessed area may provide a location on which to apply a conductive material to form a joint that electrically couples the capacitive element to a ferrule of the filtered feedthrough element.
