What type of cap is this?
It's super small and there is no writing. There is also no schematic where it came off of.
It's for an class d audio amp board out of a Chinese made Bluetooth speaker I think it's a zener but how do I know what value!?!?! |

Re: What type of cap is this?
it's a diode.
probably not a zener because it only has a black band. probably an FDLL4148 |

Re: What type of cap is this?
First thing Id do is to check it with a meter. It should act like a diode. Low resistance one way, high the other. If it acts good, then I wouldn't suspect it without further evidence. Does it have any markings at all on it? Like on the side we cant see?

Re: What type of cap is this?
you need a test circuit if it isnt shorted or open ..or simply put it back in and check voltage across it .
