Detecting an imminent failure of a power supply. An internal computerized component periodically reads a set of measurements from one or more sensors affixed to a power supply. The internal computerized component and power supply may reside in a variety of different technical contexts. The internal computerized component analyzes the set of measurements using, at least in part, a weighted set of factors, to detect the imminent failure in the power supply. The weighted set of factors may be updated or revised over time and may be specifically tailored for use with specific types of power supplies.

A capacitor is described. A casing for the capacitor comprises a container having a face wall joined to a surrounding sidewall extending to a annular edge defining an open end of the container. An inwardly extending protrusion is located intermediate the face wall and the annular edge at the container open end. A partition plate is supported on the protrusion to thereby provide a first capacitor enclosure bounded by the face wall, the surrounding sidewall and the partition plate. A cover plate is secured to the annular edge to close the open end of the container and provide a second capacitor enclosure bounded by the partition plate, the surrounding sidewall and the cover plate. An anode, for example of tantalum, and a cathode active material, for example of ruthenium oxide, reside in capacitive association with each other inside each of the first and second capacitor enclosures. A working electrolyte is also contained in the capacitor enclosures. Finally, leads extend from each anode through insulative seals structures supported by the casing for making electrical connection to the capacitor.

An electronic component includes: a capacitor array including a plurality of tantalum capacitors arranged linearly; and a fixing member supporting a first surface and both side surfaces of the capacitor array so that the plurality of tantalum capacitors are not separated, wherein an area through which adjacent tantalum capacitors in the capacitor array are in contact with each other is 90% or more of an entire area of a corresponding surface of the adjacent tantalum capacitors.
