Help!

VTX TS832 burnt component - please help


Hi guys,

Last time I plugged my TS832 video transmitter to power, it blew up (I suppose I must have reversed the polarity...).
The damage seems to be only on one component, which is fried. I'm keen to replace it, but I'm unsure what component it is.
At first I thought it was a capacitor but it's been pointed to me that it might be a zener diode.

This VTX is fairly common, here's the link to the product I bought
HERE

It's not labelled as a Boscam brand but I think it's the same design?

[U]Could someone who has this vtx have a look at the inscription on component, or take a picture ?/U]
I am attaching a picture showing the faulty component.

Thanks in advance

Alright after reading this thread on diydrones it looks like it's an inductor.

apparently 10uH but I don't know what current it's supposed to support.
I've had a look and found this component which supports 590mA.
The transmitter is rated at 220mA and I'm guessing I need to add the current consumption from my camera which is unknown - a similar camera seems to be rated for 150mA.
Hopefully this should be enough even if I add an OSD in parallel on the output.

I'm ordering the component now

Did it work?

Yes, it worked
Something else must also have suffered since the output voltage for the camera side is now around 5V, but that's ok, I power the camera directly from my 12V regulator
The transmitter is now working well again
