in the face.
first bulging small smd i have seen.

Re: icom v8000 bulged smd caps

what voltage is it, and dont say 50.

i'm just thinking as it's only 2.2uf a tant may be better.

Re: icom v8000 bulged smd caps

i will use 25v tants.
highest voltage is +5.

Re: icom v8000 bulged smd caps

Have you measure it ? I mean, is the device not working right ?

Re: icom v8000 bulged smd caps

How old is that thing? Might pay to replace the lot. I recently replaced all the SMD electrolytics in a Roland KR3500 because after many years they were ALL leaking, and for some it wasn't even obvious because the plastic base hid the evidence.

Not one was bulged, either.

Re: icom v8000 bulged smd caps

i'v never actually seen one bulged, just leaked.
i didnt think the bung was good enough to let them build enough pressure to bend the can.

Re: icom v8000 bulged smd caps

Some of the early SMD electrolytics are prone to failure, especially in devices which can get hot inside.
I am also curious if there were SMD electrolytics which were not solvent resistant.

Interesting. Also, they seem to look like they were made by Panasonic. The text font and clear (easily visible) lettering reminds me of them.

Perhaps there is a faulty circuit design? Or maybe the cap was manufactured incorrectly. (I see it's plastic base and band match the other caps, but maybe it was marked the wrong way around)

But, damn, looks like that thing is ready to launch!!!

How old is the device (radio?) that this was in?
