    Ok I was working with a PC motherboard and found some of these radial PHT type electrolytic capacitor ,what I found weird is that the marking on them is with 3 digit code like SMD electrolytic capacitor ,for example "221 16V" i.e.. 220 micro farad 16 volt...

    Did you people came across these kind of marking on a radial PHT type electrolytic capacitor before?

    No, but 220uF/16V seems correct.
    Can't id the second one except the 6.3V rating.

    Notice the bulging tops on those caps. Doesn't look good.
