    Hi,
    Trying to repair a board. Found 2 burnt capacitors. All they have on them are 471 2kv.
    So I purchased what I thought they were. Upon inspection the new ones have b 471k 2kv.
    They are slightly different and smaller.
    They're from an inverter welder, and I know the cause of them burning, so that's not an issue.
    What I need to know is:
    Are they different? If so, what should I be ordering? Pics attached

    B is the temperature characteristic.

    Thanks, but what I really want to know is that the new ones are 471k, whereas the original are 471....No k.
    Looking into it further, I found that 471 also brings up 470pf capacitors which are exactly the same as the original, and do not state they're 471k, just 470pf and 2kv.
    Is there a 470pf 2kv capacitor without
    the 471k? Why do the 2 look different?

    Ok, got it!
    K is the tolerance.......that's what was confusing me. The original are 3 yrs old, so I'm guessing newer are smaller.
