Hi,
I have came across a pdb used in quad-copters. I accidentally busted one of the components by applying reverse polarity. Could any of you here please tell me what components is this? Can i replace this ?

Probably a tantalum capacitor. Ta caps have the + lead marked.
Diodes would have a band on cathode. Most other chip caps are non-polar.
