What is this for a capacitor?

Hello,

My internal display of my system is not working.

The MacBook Pro only boots up with an external monitor. Once I open the lid, to activate the internal display the system freezes.

I took out the logic board and found that one capacitor is broken on the logic board. I cannot find out what type it is.

Maybe someone knows what it is? Attached you find a picture of the capacitor. Its marked with: 686 16 K 451.

The Board Number is: 820 3662-A

If you can supply the board number (820-xxxx) and add a picture including a bigger portion of the board I'm sure someone will be able to help with more detailed info

@blob810 that is a 68uF 16V 20% tantalum capacitor in a CASE-D2E package. The one in your comment has the same values but looks like the wrong package. Looks like mouser has those
