Tantalum capacitor scrap - Page 10

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!

Hope the pictures help everyone!

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.

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?

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

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."

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

So today I started pulling some goodies myself. It's not much, but it is a start:


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

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

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?

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

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.

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?

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?

Yes please
