Tantalum capacitor?

I have been doing some research on Tantalum capacitors and am still having trouble distinguishing between them. Are any of the capacitors in the picture Tantalum and if so which one?

I have looked but honestly they all look the same to me

The other day I saw posts from eric where he had pics. Now for the life of me I can not find them. Can someone help

Thank u mechanic. I read that whole thread the other day and reread it. Decided that it was gonna be more of a headach than its worth. But I decided to read through it again and look at erics pics again and give it another try. Prob gonna get my head hurting again

Glad I'm not the only one that is STILL having trouble identifying these. Actually seeing them on the board in the picture above is actually a great help because it puts it into scale. I know that it would be a lot of work for someone who knows what they are doing, but a series of pics of the tantalum caps on the boards would help some of us spot them in the wild.

I don't know what pics ur talking about. I wished I could see them. Maybe it would help me out some. Still having trouble. Maybe I'm over thinking it, but I first check to see it the number starts with a c then ####. Then I check to see if there is a + or a line to mark the positive, then check to see if at least one lead is magnetic and I think I might have some, but don't know. Sent etack a pic to see. There is so many different things on the boards that look rright but not. My head is spinning and I am out of wiskey. Merry X mas everyone

Just wondering if only ta caps are magnatic. Or if other ones are too. I have pulled a few caps off. They are similar in size and shape, just different colors. Some have 1 mag lead some both and some none.


Did u get the pics I sent u yesterday. Thanks man. Dennis

Got my head hurting soo bad. Had to break open the wifes homemade pineapple wine!!!!!

I found a few on some of my boards today and weighed one, the ones that I have weigh 0.10 grams so by my calculation it will take around 4,500 to make a pound. Not sure if these are worth saving. Has anyone sold some and got a count on how many it takes to make a pound?

Those round yellow caps are not tanti's. The polarity would be marked on the board too. The Tantis that look similar to this look just like a dollop of paint, you can't really see whats underneith from outside it.

The (+) sign on the capactor is the 'telltale' to Tantis.
I found some info a few days ago that gives me the impression that some of the Tanti caps that are in Ali cans, are 'wet' capactors.

The brown rectangles in front of the big blue capactor are SMD Tantis. I'm not sure if the lighter brown ones are, I think they are, just not 100% sure.
The little black SMD's that are the same size, are resistors.

Hey tack, great thread and I'm learning a lot. So is it better for you if we separate the different styles or do you care. Was going to start a jar for the surface mounts and one for through the board but if it doesn't matter to you then I'll probably save the bench space and put them all in one.

Also I'll be incinerating chips and monolithic ceramic caps for refining. Can the tanti caps be tossed in with those and the pellets recovered, should they be burned separately, or is it even worth the effort to do this?
