I'm curious as to how I'm doing so far:

And are all of these Ta? Seems some have the same #s on top but one has a + sign by it, one doesn't:

The can cap in auminer's 1st pic ic not a Ta cap. look at the (+) and the line on the opposite side.
Thanks everyone for saving them and taking the time to discus this. I an here to help and answer any question.

Has anyone sold these yet.....I looked at some boards that looked like they had these on them and just got more confused.....Tack you seem like a super patient guy and hope you get what your looking for I just don't think it's for me sorry
Thanks I have had some sale not like I had hoped but then no one was saving them till I said I would buy them.:cool:
As far as being patient I am a stay at home dad to 6 kids I think I loose my patients all the time.:D
If you just save the easy yellow ones I'm cool with that. people tend to make there life as difficult as they want. Most people on this forum don't take there boards apart so I'm looking for the person that bought a few pounds at auctions and need them moved or work at scrap yards and get a bunch in. But I will help anyone make there money too.
Thanks again
Eric
So the yellow square ones in the pictures are what your looking for.......I process a ton of crt monitors and old apple crt/computers......Mabye I will take another look
I figured that you were looking for people that get them from HAMfests or liquidators either still on the reel or in stock room bins. True?Quote:

Are you a HAM guy? If so let me know. I live buy one of the biggest HAM fest in the country so I think I will hit it up this year.:cool:
Eric
OK I'm back after letting my head rest. Do you buy only the pellet or do you buy the whole cap? If you buy the whole cap I will save some up if not then it's not worth it to me. Seems like it will take alot of these to make a pound and even more if it's only the pellets. I have or can get the ceramic ones that look like a disk that has been dipped in something.
I will buy the whole cap I have different prices on the can style, I will help any way I can.
It does take quite a few to make a pound.:cool:
Eric
Not a radio guy, but ham fests are good places to buy old electronics. A lot still look for the old 386/486 pc's for programming old units.Quote:

Big TA cap? Got some of these out of some old (70's) radio equipment.
No I'm sorry the part # makes it a GE Al electrolyte Cap.Quote:

We're going to question you to death here, etack... THANK YOU for your patience.
So we've ruled out the big guy on the left, bummer... as to the kind circled at the far right, will all similar looking (that is, round off-yellow) Ta caps have the indicator as to which leg is positive? I see alot of similar appearing caps on boards, but neither the leg, nor the board indicates any polarity. I just want to make sure I'm not throwing away money... again... ;)

What I've found is all of them that look like that are tantalum... They have no shape definition other than looking like a balloon. There are similar colored ones that have discs inside that look similar, but are not tantalum. Most of the balloon type ones I find on older electronics. Newer electronics mostly have the surface mount types. Still haven't found any can style ones.
Also, I've been noticing a lot of the time that there is a mark from a felt tip pen on ta caps a lot. Maybe for double checking correct polarity.
tantalum...................

As I responded in your other post that looks like lead. and if you Google the part number you will see they are not tantalum. this is a listing for the same series not the actual part. 6 New Old Stock Large Sprague Atom Capacitors TVA 1214 10 | eBay
They are very much Al electrolyte capacitors.
Have a good day

I found this website which shows 90 different styles of TA caps. Includes pictures of each. So this should help all you guys.
Vishay - manufacturer of discrete semiconductors and passive components
That's great smvulture Thanks for the info.
Just an FYI The larger ones that are shown can be confused with large oil on paper caps. I was sent 165# of caps that look like glass filled Ta caps but had oil and paper in them only 40# were what I wanted. luckily I pay after sorting them. this is especially true with the ones with glass on both sides of the cap, or larger than size "D".
Always here to help.
Eric
I just saw that the prices have changed. Great to know!!
This helped me. Look where wire is welded to the middle inside.
