So as a complete rookie to this part of scrapping. It IS ok to mix the black and yellow together? I have them separated because I wasn't sure they could be mixed. Thanks in advance!

It is absolutely ok to mix yellow and black SMD Capacitors together. It is the same product.

I've been keeping up with this thread and I can identify smd and epoxy caps but I have some I'm not quite sure about. I brought home about 800 pounds of old high grade telecom boards the other day and see a lot of these caps on them. I think they are tantalum but not sure what kind.

Tantalum Black & White Inserts

As far as the black and yellow "bullet" capacitors go, what are tell tale tantalum markings? Just a positive "+" sign at one end? Thanks!

Mainly the positive sign markings yes.

The tantalum inserts, what is the price per pound? Found some that look similar to your picture, the ones I have are made by the KEMET company, the data sheet calls them "block tantalum capacitors", I'll post a picture when I get some time. They are a through hole, rectangular "block shaped", yellow or black capacitor (5/16" h x 1/4" w x 1/8" thick).

I also would like to ask if those bullet capacitors have to have the actual positive + sign or does a white stripe denote that as well? I'm just getting into the electronics side of the scrap bis and I do have access to many types of junk electronics. I've been doing a lot of research lately and this tantalum capacitor stuff seems the most in-depth as far as identifying them. Last question for now is on the black smd type. Do they too have to have the actual positive + sign or is rhe stripe an identifier as well? Also, the boards are always marked with a "C###" ? Thanks again!

Grade B- Only because I was told a check was mailed and didn't receive it or any other contact for 10 days or more and the shipment was a test pack, ( THIS HAS BEEN RESOLVED QUICKLY BY TR)

RECOMMENDATION, YES I WILL USE THEM AGAIN NOW THAT PERIMETERS ARE SET.

A+ ON EDUCATION TOOL AND PARTICIPATION. MCW.

P.S. PLEASE NOTE: TR HAS BEEN UPGRADED TO A STATUS BY US BECAUSE OF THEIR QUICK RESPONSE IN RECTIFYING A SMALL PROBLEM. mcw

I do know that a C will denote a capacitor while a D or other letter corresponds to that component. Some cheaply made boards will not have any component markings on it.

I find the tantalum capacitors will almost always have the "+" signs on them, especially on the metal "axial" types. On the boards themselves about 60% of the time on low grade consumer type electronics. On the high grade boards, depending on board size, almost always on both the board and the capacitors. Even a lot of the SMD's will use the solid line and a positive sign on the capacitor. I have yet to find a tantalum capacitor that does not have a magnetic pull, so here again a magnet is a scrappers best tool.

Thanks olddude for the feedback, been waiting for a few more members to have used this buyer. Especially those of you on the east coast, before this "left coaster" does and now I think it's time for me! I like all of his pretty photos.

Those Tantalum Inserts we can currently pay $72/Lb

But, please send a picture of what you mean by block tantalum capacitors -- I am not totally sure what they are.

For the Black SMD -- The stripe is an identifier as well, Sometimes the positive sign is taken off completely from years of use.

As for the Bullet Capacitors - Honestly these types of capacitors are some of the hardest to differentiate, there are also not many of these types produced yearly.

Thank you -- We will try to figure out why there was a few day delay between mailing of the check and the delay of 10 days.

problem quickly solved by TR. We are putting them on our AA vendor list. mcw

A little update on the tantalum capacitors that I was calling "block" tat's. Don't know where I got that from, looks like a block (I guess). The KEMET data sheet calls them a "molded radial tantalum capacitor". The ones I have are T330's and T340's, not sure if the ones you pictured and call inserts are the same, but from what I can tell. they are. I will post some pictures tonight of mine (hopefully will try).

If Kemet indicates that they are Tantalum Capacitors - Then we do trust their word.

Looking forward to the pictures!

Going to post two pictures, a zoomed in for detail and five Tat's on a two inch in diameter glass specimen tray. All five came off of a X-ray camera PCB from the early 80's. Now to find some more, it does get easier once you learn the different types.

Any idea what year these capacitors were made? These are not SMD Capacitors.

These capacitors look as if they were standing on the board rather then laying on the board.

I'll try to get the date to you in a couple of hours from now. It's going to be late 70's or early 80's. My dogs are insisting I take them for their walk and I like to keep them on a schedule or I'll have a mess!

These tat's are definitely installed vertically (Standing up), the marketing on these is "compact space saving tantalum capacitors". The one I'm showing are a older design. KEMET has now put a "radial curve" on the anode side of the capacitor and now puts the makings on the top surface of the capacitor. They indeed or not a SMD, but what they call a PMD - Precision Molded Device. One of the unique identifiers for these tat's is the bottom shape. Coppied straight from the data sheet: " These standoffs, located in the base of all case sizes, provide vents for air circulation and also allow easy removal of flux residues from lead wire and circuit board solder joints."

Have to give a huge Thank You to BigBurtChino for all the work you have done on this thread. You've got me inspired :)

So today I started pulling some goodies myself. It's not much, but it is a start:
https://lh4.googleusercontent.com/-5...553-no/TCs.jpg

Now I think those ones on the left are TCs but not 100% sure on those. They are4 magnetic and had the + marked on the PCB. Are they the "bullet" ones someone was referring to on here?
Thanks,
Cheryl

Ok, excellent thank you very much for clarifying -- We can absolutely take the material then!

Those on the left are indeed Tantalum Leaded Bullet Capacitors! They are all Tantalum except ofcourse for the bottom ANALOG DEVICES part. :D

So would these "upright" block caps need to be separated or can they be put in with the other SMD's?
Same question for the pictured yellow bullet style on the other thread above?
And is it standard SMD pricing for BOTH types as well?

ScrappinRed - SMD's & PMD's I would separate, as the smallest PMD package is twice as large as the largest SMD package. Both are made from a sintered solid rectangular tantalum "slug", the rectangular PMD's contain a much greater amount of concentrated tantalum. Some SMD's utilize a Wet Electrolyte (rare, but they do exist). The "bullet's" are actually PMD's, difference the bullets being Axial leaded and bulkier. The rectangular PMD's have a higher capacitance range for their size (more concentrated tantalum) compared to the bullets. The bullet PMD's are going to be much more common and easier for us scrappers to find.

Only RecyclingTantalum can say if they can be combined. So a good question, I'm curious as to prices, are the rectangular PMD's that I have shown and the ones he showed in bulk (post 169/Inserts), the same?

I need to make a correction (sorry for error), KEMET Corp. calls them PMT's Precision Molded Tantalum capacitors. Not a PMD!

May you please send us a picture of what you mean by PMD's?

What is the price for the yellow bullet caps on left in post #189? Do they need to be separated or mixed with another type of cap?

What is the price for the yellow upright caps in post #190? Do they need to be separated or mixed with other smd caps?

There is no PMD capacitor (that I know of), that was a mistake! The post in 183 is called a PMT (Precision Molded Tantalum capacitor).

They would be the same $24/Lb -- but they would need to be separated from the SMD type Tantalum Capacitors

These are not the same as the inserts i have shown -- The inserts i have shown are actual majority based Tantalum Inserts around 68% Tantalum.

These are leaded capacitors and they most likely will have not have more Tantalum then the SMD inside of them.

They should be separated as well - as there are Tantalum Capacitors Bullets and None/Tantalum Capacitor bullets.

The price for the Bullets are $24/Lb as well.

I meant when shipping them to you. You want the bullet ones separated from the other smd's... right?
