Blown capacitor on logic board. What is it?

Long story short, my logic board went out. Started smelling like burnt electronics. Pulled the board out, and found one of the capacitors on the back side of the logic board was melted.

It seems like it would be fairly easy to replace, I just don’t know what capacitor it is, or where to find one. I know it looks like a D2E Case Tantalum capacitor, but beyond that, I’m not sure.

Thanks in advance!

The Cap is one of a group: C7370 which is a 68UF 20% 16V Poly-Tantalum in a D2E case

Thanks a ton! I do have a follow-up question. (see second picture above) The blown capacitor is opposite the metal block (R36 446 RA7). I don't know exactly what that component is. Can't tell if they're connected or not.

Just wondering if there's anywhere I should check for a short or anything before replacing the capacitor?

Thanks again!

Also, the link seems to point to the wrong thing? It pulls up a 6.3V 220UF B case capacitor?

The R36 is an inductor coil Shielded Power Inductors
