Der Deckel (3) besteht aus einem glasfaserverstärkten Epoxidharz und ist in seinem thermischen linearen Ausdehnungskoeffizienten an den des Gehäusewerkstoffes angepaßt. Die Abdichtung des Deckels (3) und des Gehäuses (1) erfolgt mittels eines Klebstoffes oder Lotes. Auf der Außenseite des Deckels (3) kann eine Kupferplattierung (7) angeordnet sein.
Abstract:
A co-connected hermetic feedthrough, feedthrough capacitor, and leadwire assembly includes a dielectric substrate with a via hole disposed through the dielectric substrate from a body fluid side to a device side. A conductive fill is disposed within the via forming a hermetic seal and is electrically conductive between the body fluid side and the device side. A feedthrough capacitor is attached to the dielectric substrate and includes a capacitor dielectric substrate, an unfilled capacitor via hole including an inner metallization, a set of capacitor active electrode plates electrically coupled to the inner metallization, an outer metallization disposed and a set of capacitor ground electrode plates electrically coupled to the outer metallization. A conductive leadwire is disposed within the unfilled capacitor via hole. An electrical joint connects the conductive fill, the capacitor inner metallization along with the capacitor active electrode plates and the conductive leadwire.
Abstract:
A feedthrough seal apparatus (230) is configured to seal an opening in a device. The device includes a case (210) surrounding an interior space, the case including the opening (214) therein to allow access to the interior space from an exterior of the case. The feedthrough seal apparatus includes a plug (232) disposed within the opening of the case. The plug is formed from at least one of a polymeric material and an adhesive material, such as epoxy. The lead wire ()234 extends through the plug, such that a first end of the lead wire is disposed within the interior space of the case and a second end extends from the plug to the exterior of the case. The plug is configured to electrically insulate the lead wire from the case.
Abstract:
An electrolytic capacitor capable of operating at 75 g or greater is provided having a case with a base and a lid, with a wound capacitor element positioned on its side, lengthwise along the bottom of the base and with the underside of the lid pressed against the length of the capacitor element, to frictionally engage the capacitor element. The case is provided with inwardly projecting surfaces, including a bulkhead at one end of the capacitor element and ridges on the lid, which function as barriers to restrict movement of the capacitor element within the case. A compartment is created at one end of the case, to allow space for terminals, which are embedded in a non-conductive support matrix.
