    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?

    down in the lower left there is those 2 yellow teardrop caps, if they have the (tattletale) + mark showing the positive terminal then there's those 2 I see. Have you looked at the pic's the buyers have posted??

    The tattletale mark I mentioned is a good indicator cause a lot of caps do not have it.

    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.

    Their kind of like a snipe, once you have caught your first one then you never forget what they look like.

    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

    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?

    it all depends on case size and style.

    I remove my Ta caps from boards when I remove my batteries.


    it can take 4500 of size A SMD but I only takes 70-80 size D can style

    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.

    Omg lol, after reading this thread and the linked ones, I went and looked at all my boards in the garage to see if this was something I'd want to add to my scrapping. I was so confused by what I was reading and looking at and then I saw how small some of these things are I decided I'd go cross eyed trying to make this work and I'd see if you would just BUY the boards from me for 20.00 lb lol. Obviously not and I'm just kidding but my serious question for you is, what do you do with the Tantalum you recover? Do you use it in your job or is that something that gets sold to a buyer like say, gold or silver would be?

    I'd never heard of this stuff before joining this forum so am curious now lol.

    The only Ta caps that is in an Al can paper Ta foil. Wet Ta caps are in Ag or Ta cans.

    The little black SMD's that are the same size, are resistors.
    The caps you are referring to are MLCCs. SMD style Ta caps are in three colors Red, Black and Yellow

    As luck would have it I have some of the rare blue SMD style caps the just surfaced yesterday.
