    You didn't mention the most unique thing about tantalum: one of its isotopes, Ta-180m! While nuclear isomers are typically very short-lived, this one is not only more stable than the ground state, it is so stable its decay has never been observed. It makes up a much smaller fraction of natural tantalum than is typical for a long-lived isotope, and is the rarest known isotope in the universe whose rarity is not due to instability. Tantalum is also the rarest element in the universe whose rarity is not due to instability

    • @GarryDumblowski
      @GarryDumblowski 7 лет назад +8

      Apparently, Am-242m is the same way, though of course it's not just straight-up stable unlike Ta-180m. There's at least been talk of its use as nuclear fuel, possibly as a fuel even better than Pu-239.
      That said though, I've been told that there's only four stable isotopes with both an odd number of protons and neutrons: H-2, Li-6, B-10, and N-14. Wouldn't Ta-180m be a fifth one?

    • @GarryDumblowski
      @GarryDumblowski 6 лет назад +10

      No, I don't mean the atomic masses are odd, I mean both the number of protons _and_ the number of neutrons are odd. H-2 has 1 (odd) proton, and 1 (odd) neutron.
      Just the same way, Ta-180m has 73 (odd) protons, and 107 (odd) neutrons, and is stable. Almost all stable isotopes except the five I mentioned have either an even number of protons, an even number of neutrons, or both.

    Great Video! As usual. Tantalum capacitors are the highest failure rate of all capacitors. Usually because the designer does not understand how sensitive they are to design conditions. You want to operate tantalum caps at nearly their full voltage rating, but not over that. Problem is, AC noise on the DC will exceed the destruction threshold. Some noise can be of a frequency far higher than you can see on your o'scope, yet it is still present. I call this noise "hair" as it can be hundreds if not over a thousand megahertz. Your 500MHz scope shows zero, yet the caps keep burning up. We (at Prime Image in the 1990s) finally bought a 10GHz scope that discovered this issue. Not only that, they burn fiercely and usually burn a hole through the PCB permanently destroying the product. Don't use them if there is any reasonable substitute available. Only as your last choice.

      videolabguy pretty much, I've had so many tantalum caps to replace on things, very true, they fry. The only exception is wet foil tantalum caps, very super reliable. modern aluminum electrytics have caught up though.

    • @big0bad0brad
      @big0bad0brad 3 года назад

      Personally I think there is a lot of batch and manufacturing technique variation; some of them seem to stay good indefinitely and some start failing in droves. But for most use cases it does not cause much damage if they happen to blow up, and the failure mechanism is pretty obvious so repairs are easy to target. Unless a lot of them are failing on one board, I think it's reasonable to replace just the failing ones with whatever type makes the most sense to you, unless it seems like further incidents could cause excessive board damage. Personally I haven't seen much smouldering-through-layers kind of action, more like popcorn going off.

    Also due to ductility and density it is used for the foil cone in shaped charges, so it has military applications (antitank rounds and missiles). Surprised that wasn't brought up regarding it's conflicty-ness.

    I had NO idea of the Voltage vs colour electrolytic property of Tantalum. 😮
    My only experience with Tantalum (IIRC, a 94%Ta alloy) was back ~1986, I was asked to make a prototype set (3 off) "heater pads". The material was ~75x75mm x 0.50mm, They were "randomly" hand cut, three sheets in an envelope with "rice paper" separators. It was smooth cold rolled with a very dark grey (likely oxide) finish. I bent a corner with my thumb and it was very soft/compliant, close to lead.
    The pattern... picture a PCB trace with a left & right bus bar / lug and two intricate sine-wave traces, one above the other, in phase, between the buses. Each of the 3 patterns had a slightly different "frequency" and trace width. (build&test 3/select 1).
    Photo / acid etching was not an option, so I sandwiched each sheet between two 6mm "ground flat" plates of aged iron (Mianite), jig-drilled the lug holes in for orientation/location, and then Wire EDM'd the patterns... in 1986, took +18hrs.
    Unfortunately, the product only used ~20% of the sheets so they wanted the scrap material returned by the m/gram. I didn't get to keep a sample.
    Also, my blueprints had the entire title blocks and notes physically removed... so I knew who it was for. 🙄
