    Sightings of bulging/leaking 400/450V capacitors in power supplies

    If anyone has pictures of power supplies (especially AC adaptors) having bulging/leaking 400/450V electrolytic capacitors, please post them here.

    I've only seen one bulging 450V unit (22uF Jenpo).
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    Never seen an high voltage cap bulging, but have had a bunch of smaler G-Luxons wich are bad, but no obviouse sign of failure (abouth 10uF 450v). Some Acer TFT`s do feature them too.

      Here is the photo of bulging 450V,330uF Electrolythic capacitor. It is from SONY Trinitron 15" TV. Main rectifier short circuit causing AC supplied to the cap...







      Enjoy ...

        High AC voltages tend to be rough on lytics, . LK is a good basic series for snap-ins.

        Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.
