Capacitor or Diode?

[jakeofalltrades12]

Hello All, I'm repairing my Lincoln welder and found this blown component, from the looks of it I believe it's a tantalum capacitor, but I am not sure what the numbers mean. Does anyone have a clue? Thank you,
Jake

Are there similar devices on the board that you can read the markings from?

It looks like you may have damaged the board removing this component. It looks like you're removed a pas with it (it's on the lead on the right hand side).

Thanks for getting back to me so quickly, I did look to see if there was similar components but no luck. You think I ruined the board? Is there a way to check the board?

It certainly looks like you have damaged the board, and this will need to be repaired. How difficult this might be can't be determined without a picture.

And by the way, that looks like an axial tantalum capacitor.

Sir jakeofalltrades12 . . . . .


Agreed . . . . . . that on the negative lead of that tantalum capacitor, that you pulled off a pad from the top of the board.
I'm going to place its value at 3 DECIMAL 3 ufd and at 25 VDC working.

Ref . . . .your center photo . . . and concentrating on the caps + wire lead . . .

Its hanging amber colored deteris . . . seems to suggest the whole board as having one heavy conformal coating, as Lincoln boards typically do.
That alone, might have made it an even harder challenge to pull from the board, in addition to the soldering aspects task.

If you can give us a close in photo . .well lit . . .just filling in the frame . . .straight on.
We might find another board to compare to . . . or you do a preliminary view of some of these . . .

VISUAL REFERENCE . . . . .

Below, yet another LINCOLN controller board and having about the same pads as yours, with this cap being 2.7 ufd at 25VDC.

You guys are awesome, thanks for all the imput. Here's some pics of board, I have not seen another one like it on the web. I was as careful as I could be but that coating was a real pain. It seems to me that the pads are intact on both sides but let me know what you all think. Luckily it was in the tightest place on the board haha.

For future reference you don't have to 'fully' remove the damaged part - indeed, cropping the leads either side of the blown component would have left you some 'easier' leads to solder a replacement part to.

You have the similar component on board. Just take a careful look and use the internet for browsing what it might be.
