A motor controller assembly is configured for use with an electric motor and includes a controller and an absorbent pad. The controller includes a capacitor with a capacitor shell and a liquid electrolyte contained therein. The capacitor shell has a frangible rupture area that opens during a capacitor rupture event to permit the discharge of liquid electrolyte from the capacitor shell. The absorbent pad overlies the rupture area to collect discharged liquid electrolyte.

A hermetically sealed feedthrough assembly for an active implantable medical device having an oxide-resistant electrical attachment for connection to an EMI filter, an EMI filter circuit board, an AIMD circuit board, or AIMD electronics. The oxide-resistant electrical attachment, including an oxide-resistant sputter layer 165 is disposed on the device side surface of the hermetic seal ferrule over which an ECA stripe is provided. The ECA stripe may comprise one of a thermal-setting electrically conductive adhesive, an electrically conductive polymer, an electrically conductive epoxy, an electrically conductive silicone, an electrically conductive polyimides, or an electrically conductive polyimide, such as those manufactured by Ablestick Corporation. The oxide-free electrical attachment between the ECA stripe and the filter or AIMD circuits may comprise one of gold, platinum, palladium, silver, iridium, rhenium, rhodium, tantalum, tungsten, niobium, zirconium, vanadium, and combinations or alloys thereof.

The instant disclosure relates to a stacked-type solid electrolytic capacitor capable of increasing welding effect and a manufacturing method of the same. The stacked-type solid electrolytic capacitor includes a plurality of solid electrolytic capacitor units, each of which has an anode part and a cathode part connected to the anode part, characterized in that the anode part is formed with at least one buffering via-hole in a welding area thereof. When each of the anode parts is compressed in a welding process, the volume of the corresponding buffering via-hole decreases accordingly. Therefore, the soldering performance of the anode part solid electrolytic capacitor is enhanced and the connection stability is increased.
