I’ve heard a lot about these little things, but still not sure what to look for outside they are yellow. Can anyone shed some light on these and give me all your expertise on the subject? thank you..

Check YouTube, there is a scrapper named OriginalFeets, he has a few videos on tantalum capacitors. They are informative and funny, he is the go-to guy on a lot of E-Scrap questions.

The yellow ones are — The other ones some are and some are not.
December 13, 2014 at 12:10 pm #1551
in the first picture those are Tantalum
December 14, 2014 at 8:24 pm #1552
Whats the easiest way to get them off? I usually take them off with pliers but sometimes they break
December 15, 2014 at 7:57 am #1554
So basically anything with the + sign is what we’re looking for? If it doesn’t have a +, then its not Tantalum?
December 15, 2014 at 2:14 pm #1555
It is ok if they break but best way is too use a torch to heat the opposite side of the board.
Everything that has a + is Tantalum – but, it is not neccesarily true that Tantalum Capacitors always have a + on them.

Capacitor 3 — Hermetic / Axial / Radial Tantalum Capacitor
Capacitor 4 — Leaded / Tantalum Capacitor – We consider these in the same category as Tantalum SMD
Capacitor 5 — Epoxy / Ceramic / Dipped Tantalum Capacitor
Capacitor 6 — Epoxy / Ceramic / Dipped Tantalum Capacitor
Capacitor 7 — Epoxy / Ceramic / Dipped Tantalum Capacitor
Capacitor 8 — Epoxy / Ceramic / Dipped Tantalum Capacitor

Ill take some pics of some and post it

I believe they are except for the one that is indicated electrolytic.
I am pretty sure as it has a positive sign on this and these are mostly tantalum.
Can you please take them out of the wrapping and take another picture.
December 22, 2014 at 10:01 am #1590
in that last pic, does the T mean tantalum, like all those yellow ones?
December 22, 2014 at 10:13 pm #1594
yes that is correct
December 23, 2014 at 9:16 am #1596
dang, I’ve been just throwing them all away not knowing. Thanks for the info.
December 23, 2014 at 9:20 am #1597
December 23, 2014 at 9:47 am #1599
Please take a few better pictures of the black capacitors they are the only ones that are possibly Tantalum.
December 24, 2014 at 6:59 am #1603
December 24, 2014 at 8:13 pm #1606
They are all the same the one is just rolled so you cant see the+
December 30, 2014 at 6:20 pm #1632
Thank you, everyone!! this is exactly what info I was in need of…not the purpose of this visit, but definitely desired info!!

Please correct me if I am wrong,the only tantalum I see on all the picture’s are the mustard yellow ones (smd’s surface mount capacitors)?Where did the board from the first picture come out of?
January 12, 2015 at 4:03 pm #1696
There are black SMD Capacitors on those boards as well, but it is hard to see on the pictures.
The first board came out of an old Telecom Industry item.

Hello Chris — Unfortunately none of the capacitors on the board are Tantalum Capacitors.
January 19, 2015 at 9:33 am #1720
Jason — all of the yellow capacitors are Tantalum and the Brown ones are MLCC Capacitors.
That is a Great Board!

Does the MLCC Capacitors have value?
June 3, 2015 at 9:59 am #2041
Yes MLCC SMD Capacitors have a value of $16.50/Lb

Do yall know of any good places to sell your tantalum capacitors?
August 8, 2015 at 9:38 am #2171
September 22, 2015 at 10:43 am #2365
does the capacitors have to be separated before shipping?
September 25, 2015 at 8:32 am #2384
Yes it does need to be separated.
September 26, 2015 at 7:28 pm #2392
sorry for all the questions, but I read that if the number on the board next to the ‘capacitor’ means its tantalum. Is that correct?

October 16, 2015 at 1:19 pm #2472
What condition do the Tantalum Capacitors need to be in for you to buy them?
Also can you help me out with ID’ing these different compositors?
What type of compositor are these?
I did read your post ID’ing other Tantalum compositors. I am just learning about these things and appreciate the help.

I apparently have been going about the collecting of scrap capacitors wrong over the past year in regards to ceramic & tantalum :/ I thought I read in a few places that all ceramic capacitors have precious metals (a lot containing tantalum too) and that if I am scrapping circuit boards, that I should collect all ceramic & epoxy caps without the need for separation. Basically if there is a “C” on the circuit board, snip and collect. The tall cylindrical aluminum electrolytic caps of course I learned go to aluminum scrap though.
So… after reading this thread, am I right in the assumption that ceramic & those brittle powdery round brownish-orange caps (tiny rectangle surface mounted MLCC excluded) as well as those bulky rectangle plastic-cased Molded Ceramic contain no precious metals or scrap value and I should leave on the boards for board recycling? Or is there in fact a market for those? I included a picture of a bin of the caps that I have collected.
July 13, 2017 at 12:36 am #3115
C Means Ceramic and Ceramic has absolutely no value in capacitors produced after 1998.
Before 1998 the material contained Palladium in the capacitors and this was replaced by Nickel/Leaded Alloy – Which means it is not worth it to scrap at all.
We only purchase Tantalum Capacitors and even though we see Tantalum Capacitors in your mix there is much more Ceramic then anything else in your pictures.

>PC-Recycling Warsaw IN.
The answer of “no” that TantalumRecycling gave you in response to the value of the capacitors in your picture is not entirely correct. I think what they meant to say was “not as far as tantalum is concerned”.
The fact of the matter is that the first two capacitors in your pictures (#1 & #2) do contain a precious metal, silver. If you notice the two legs on either side of the capacitor that connect to the PCB, on the other end of the legs (where they enter the epoxy coating surrounding the capacitor), each leg will connect to a silver disc which then acts as a contact to the capacitor itself.
There’s a silver disc which the leg entering the capacitor connects too and there is a silver disc which the leg exiting the capacitor is connected too.
I have attached a .pdf copy of the chapter that covers capacitors from the book “E-Scrap Parts Manual”. Not only does this Capacitor write-up go into great detail as to all of the different types of capacitors available, it also lists what they are commonly used for; where you might find them and the different equipment they are used in; their intended application. it also lists any and all precious metals that might be used in their construction along with the other materials used in their construction. Every capacitor in the chapter is backed up with several different pictures several pictures for easy identification.
This chapter on Capacitors is perhaps the most informative and complete resource ever made available in regards to capacitors

Oh you have NO idea how much I appreciate that attachment Darksky! That attachment has explained so much more than all the tid bits I have been able to occasionally find on the internet in various places. Some even seemingly contradictory to another. That attachment has what appears to be all the info, and picture examples, one should need all rolled into one location. And when Tantalum Recycling said that the “C” on circuit boards stood for ceramic… I knew I can’t rely on their knowledge too much since 95% of circuit boards print a “C” to indicate Capacitor component… not type of capacitor. I will be doing some separating of what I have thus far before my pile gets too out of hand. Because there’s apparently more different types than I thought too. Again… thank you so much!
