    I'm frustrated to discover that a couple of 1000uF 16V electrolytics
    that I bought from Jaycar a few years ago to repair a video card now
    have bulging tops and will have to be replaced. They are "Suntan" brand.
    It appears from a search that I'm not the first to have trouble with them.

  2. **I ceased buying 'mission-critical' components from DSE and jaycar many
    years ago. Caps from WES are decent enough for day to day service and
    Farnell (no, I refuse to call it Element 14) or RS Components can be traced
    and are of high quality.

    I'd feel a bit silly ordering 2 capactors online, and having them sent
    by courier.

    Still, if that's what it takes to get reliable components...

  4. **I see your point. Try WES Part #1000TKR16. It is a 105 degree C component
    and I've found them to be excellent quality. Very low leakage too.

    Well, I don't actually know what role they're performing, but there's no
    inductor in sight, so they're not part of an SMPS.

    And being as this is a video card, it's power supply inputs are DC.

    Both motherboards and more powerful video cards have DC to DC SMPS that
    converts 5V (maybe 3.3V) into whatever Vcore the CPU/GPU needs. They
    need low ESR electros.

  8. **If you wish, I can add a couple of caps onto my next WES order (Thursday
    or Monday). I can then post them to you at cost. For the values you cited,
    that's $0.45 each. If you want the caps that are specified for SMPS, they're
    $0.60 each. Add a Buck for postage to you.

    Thanks, but no. I'm not even using the video card at the moment. I won't
    repair it unless I find a reason to use it again.
