Tantalum capacitor scrap

Hello - I have verified that the second picture is Ag/Ta as well. So the top is Axial Hermetic Capacitors and the bottom two types are Ag/Ta Capacitors.

Okay a few more questions about the difference between axial hermetic, wet, and silver.

-Plain hermetic will be shiny, and no crimps?
-Do the "end cap" colors matter? red, black, white, metallic?
-Will wet and silver always be crimped? Crimped once or twice?
-Are all "dull" crimped ones silver?
-I had thought the "dullness" came from the plastic wrap/case on some of them?

I'm not trying to be a pest, I really want to be able to sort these correctly and maximize my money since there is a large price difference between these categories. I also want to stop missing these little buggers on any future boards.

I have more photos of different similar types, would you prefer I load them in your thread with my questions or start a separate thread?

Thanks =)

Plain Hermetic does not have to be shiny but it has no crimps - the outside material is Brass.

The end caps do not matter as it all depends on the age of the actual capacitor - When you will see a color opening on the top of the crimp it is almost always certainly Wet Capacitors.

There are Silvers that are not crimp but not many of them - They are usually crimped only once which is considered to be the top of the capacitor.

I am not totally sure what you mean by dull crimped ones - The Wets that are gun metal looking are Tantalum/Tantalum Wets and then there are also Copper outside wets but these were only produced for an extremely small period of time.

Please load the pictures it would make things easier to explain.

The capacitor in the last two pictures ABOVE was the first cap I found that appeared to have two crimps.

Here are some photos of other tantalum caps that I'm trying to sort. Please let me know if you need additional images, it is hard to get the dull/shine to show well...

...closer 5-7, and #9




...closer 8-10

Thank you very much for the detailed picture this helps much with explaining the differences in types of capacitors.

1, 4, 5, 9 & 10 are all Axial / Hermetic Tantalum Capacitors

2, 3, 6, 7, 8 are all Ag/Tantalum Capacitors
