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.
