    The reason they would have different part # would be so the parts dist. could tell the difference between 150mf and a 15mf. Can't be lumping them together. I just used the numbers as an example, also the caps. could have different voltages in addition to the microfarad rating.

    I just wish I could find a list somewhere that had part numbers next to silver, wet, or hermetic axial so I could sort them correctly! There is a HUGE difference in price...

    Maybe that's something you could do. Even if you just use it for yourself. Put it in a spreadsheet with a simple search where you'd enter the number into your spreadsheet and it'll bring the number up for you and next to the number would be the type of TA cap it is. It'll make your TA search much easier in the long run. Time=money. Hope you get it figured out. Looks like you have a great start!

    Thank you for the pictures -- All of these capacitors are AXIAL / HERMETIC Capacitors

    Hmm... ok now I am confused. You said in the first round of photos on the other page that the plain hermetic caps(I understood this to be your axial/hermetic $24.25 classification) would NOT have crimps, and yet all but one of these cap sets HAVE crimps and you classed them all as axial/hermetic. Can you please help me understand? Thank you

    Axial just means that the leads are coming out each end , kind of like an axial on a car.
    The ones where both legs come out the bottom are called radial.

    I'm half tempted to pay you to create a u tube video on how to tell the difference between the caps cuz I'm not quite lost yet but I think I'm losing it.

    Thanks Mech I understand the leads, but it's the crimps! The actual crimps/crease in the caps. My confusion is that I understood the OP on the previous round of pics to be saying that axial/hermetic caps would NOT have these crimps/creases and thus any tantalum cap with this crimp/crease in the actual cap would have to be Wet or Silver. I am desperately trying to grasp the difference between the Hermetic Capacitors - $24.25/Lb, Wet Tantalum Capacitors - $50/Lb, and Ag/Ta Capacitors - $90/Lb so I can sort this batch appropriately and send them in to get paid

    Hello - These are not the same type of deep crimps as the Wet Tantalum Capacitors and the Ag/ Tantalum Capacitors, If you look closely there is no real indent the piece that you see on the Hermetics is just the magnetic attachment on it. Also - It has a different color then the Hermetic / Axial capacitors. The pictures of the Hermetic have a Brass shell on the outside.

    I have attached a picture showing the difference between Hermetics and the Wets -- The Wet Tantalum Capacitors and Ag/ Tantalum Capacitors look exactly identical only a different color.

    You will also be able to tell which one is Wet or Hermetic Tantalum Capacitors by the weight of the actual capacitors.

    Not sure if anyone else has sold to these guys before? I sent a shipment to them over the weekend and am waiting to hear how I did on sorting and weighing my first batch. Will post a review of the company and the selling/payment process after we complete the transaction...

    So I've had a ton of new old stock stuff from an auction and I'm completely lost. This is one if the many things I have. Are these epoxy caps?

    These capacitors use Mica for the dielectric. Mica capacitors have good stability because their temperature coefficient is small. Because their frequency characteristic is excellent, they are used for resonance circuits, and high frequency filters. Also, they have good insulation, and so can be utilized in high voltage circuits. It was often used for vacuum tube style radio transmitters, etc.
    Mica capacitors do not have high values of capacitance, and they can be relatively expensive.

    Pictured above are "Dipped mica capacitors." These can handle up to 500 volts.These capacitors have no polarity.

    So after looking, I found that they contain silver so maybe some value. But not a buyer here.

    As Mechanic688 has indicated unfortunately these are not Tantalum Capacitors.

    My review as promised:

    *Several positive email communications back and forth with questions and verifying types of material, as well as my research and questions on this thread.
    Fri 10/10 Emailed TantalumRecycling with the totals I had ready to ship. Verified the shipping address and they requested I send an invoice with my material.
    Sat 10/11 mailed priority mail flat rate envelope with material and invoice. Also emailed a copy of invoice and notified them I had made the shipment.
    Tue 10/14 received confirmation email that my material arrived and that our weights matched. I had requested to be paid by check so they mailed it out 10/15 morning
    Mon 10/20 received check

    Smooth transaction with excellent communication. I will definitely be doing business with them again. The turnaround time would have been faster had I not started the process on a Saturday! I highly recommend selling your material to Ronald and Mark. Hardest part is identifying and correctly sorting the material!!!

    So, I only harvest the yellow, square kind because they're easy to spot and I'm SO new at this. My question is: What are they called on the price list? What category do they fall under? Sorry if this is a dumb question.

    The yellow capacitors are -- Tantalum SMD Capacitors.

    These are Surface Mount Capacitors just like the Black Capacitors

    We can provide more pictures if you email us at mark@tantalumrecycling.com
