7777 Black, what could it be ?

Hello,

I got a blown power supply module, i found a damaged fep30dp. Actually there is a component that i don't know what it is, it's black, shaped like a diode with the reference 7777 on it. I tought it was an inductor, but i'm not sure, the inductors i have got no marking on'em.

Thanks.

Post a good picture.
