It's an inductor.
Do not know where you are in the world however you can find them at Digikey / ebay / amazon / aliexpress and so on. Where you are will determine the best place to buy it.

You might also have some luck googling for local electronics repair places near you, they will probably have some around.  

Did you knock it off or did it fall off or did it heat up and crack?

this T9+ was working on a friends house in venezuela (I was not in venezuela by then) and to be honest I think he did not care much about the maintenance of it.. he told me one day the hash rate just drop off half.  

Now that I have the T9 in my hands I teared it down and noticed this issue... Actually all 3 boards are in the same condition (inductor drop off)

I start thinking the problem are not the inductors, this is just the result of another bigger problem :/

please take a look of these images and tell me what you think.. thanks!!

Hard to tell from just images but that looks like corrosion. They do get hot and if there were running in a humid environment that could be the issue. More resistance = more heat = more power needed = more heat. Add in some moisture that is being cooked off by the heat and generating more corrosion and it's going to pop.

Unless you have just about free power you are going to loose money running a T9+
Back of the napkin math at $0.02 a kwh are you are generating 0 profit. Anything above that cost you are loosing money.

You can find this component at Zeus Mining. https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=2397
And I think you need to check the T9+ hash board repair manual. The manual has instructions on the clamping circuit. If L5 falls, it is also necessary to check whether Q2, Q7, and U88 are damaged.

Take note zeusbtc is not selling 1pc their minimum moq is 20.
Only buy in your local electronic shops near you to buy 2 or 3 pieces as extra if ever the first replacement is busted.

Also, I do recommend to follow the instruction under link given by Rodemi under the name T9+ hashboard repair for step by step troubleshooting because it might be not inductor issue.
