Does any know what kind of cap this is?

What kind of cap is C814? This board from car GPS, C814 connected to fat traces as you can see.  It's shorted and I need to replace it. Thanks.

  • It is a surface mount film capacitor.

     

    An example would be the SMC series from KEMET. Though, I am not sure who's makes that capacitor (family).  However, the reason they tend to get used is that they have relatively high rated DC voltages. E.g., 250 Vac, 300-400 Vdc. While you could get the same CV in a ceramic, it would be physically as big, if not larger. And something that big would be prone to flex cracking.

     

    For a replacement, you have the 184J suggests it is a 180 nF ±5%. You should be able to measure the physical case size to find something similar. As for rated voltage, if you can't make measurements or determine from the power supply module what it outputs, I'd suggest looking for the highest rated voltage for that measured case size and capacitance rating.
