Abstract:
A wet electrolytic capacitor that contains a cathode, fluidic working electrolyte, and anode that includes a sintered porous pellet is provided. A dielectric layer is also formed on a surface of the pellet and within its pores through anodic oxidation. The present inventors have discovered that through selective control over the anodic oxidation process, a substantially amorphous, low crystalline dielectric layer can be formed which, among other things, exhibits a leakage current that is smaller than previously thought possible for the high voltage capacitors employed in implantable medical devices.

Abstract:
A module containing a plurality of active capacitors and a sacrificial capacitor is provided. The active capacitors and sacrificial capacitor are aligned along a horizontal direction so that the side surfaces of their cases are parallel to each other. The particular arrangement of the active capacitors and sacrificial capacitor results in a module configuration where the anode terminations for the active capacitors and an external component of the lead frame for the sacrificial capacitor are coplanar so that the module can be mounted to a circuit board via the anode terminations and the external component of the lead frame in a mechanically and electrically stable manner. Further, the center of gravity of the module in the length and/or width directions can be located at a midpoint of the overall module length and/or width, which enhances the stability of the module when mounted to a circuit board.

The paired elements are electrically connected in series by various techniques including brazing for hot side and/or also cold side connections, and soldering for cold side connections while being thermally connected in parallel. In selected embodiments, electrical and mechanical connections of the elements may be made solely by mechanical pressure.
Abstract:
A crystal controlled clock oscillator resin encapsulated in a surface mount device (SMD) package (52-58) incorporates on a lead frame (42) a crystal oscillator (16), an integrated circuit (30), a power supply filter capacitor (20) and, optionally, a feedback resistor (18). In the fabrication of the device, resin is injected at a position and in a direction relative to the components so as to minimize disturbance of the lead frame and the components mounted thereon.
Abstract:
A binary electrical fuse (13) is comprised of a core wire (20) which is preferably relatively rigid, has a high ohmic resistance, and a high melt temperature. The core wire is clad with a metal (21) of substantially less rigidity having a low ohmic resistivity, and low melt temperature, i.e. in the range of from about 230 degrees C to 700 degrees C. The resistance of the core wire is at least about ten times the resistance of the cladding and preferably twenty or more times the resistance of the cladding. In the course of a fusing cycle the cladding metal will melt and pool, leaving the core wire as the sole conductor resulting in a rapid blow of the fuse due to the sudden high resistance load presented by the core wire.

The control circuit is further configured to control operation of a second pair of the switching devices that is different than the first pair to couple the balancing capacitor across a second ultracapacitor of the plurality of ultracapacitors to transfer at least a portion of the electrical charge from the balancing capacitor to the second ultracapacitor.
