    Hi,

    I have several thousand 4.7 uF 35v gumdrop tantalum caps we don't need
    any more. Anybody want some?

    John
     
  2. Sure. I'll pay postage for a bunch of them.

    Why on earth would you stock several thousand of anything?

    ** Maybe to get a few of them that actually work OK ;-)

    Left over from a project, value changed!

    We do, at present, have well over a million parts in stock.

  7. Well I don't wish to appear greedy, but yeah, put me down for 990,000
    of them, John. ;-)

    You have an app. using tantalums, where the value makes that much
    difference? If I were doing any TTL prototyping these days, I'd
    ask for a handful or so, but I'm not, so the best use I could come
    up with at the moment is to fill up that empty drawer in my Akro-Mils
    parts cabinet. :)

    Thanks!

    Are they blue or orange?

    Bright red. Sort of tacky, actually, which is why I don't want them on
    my boards.

    Tooo right by half.

    Pale blue on a blue solder mask might work. You might accept the right
    subdued shade of green but orange is not going to cut it. Bright red doesn't
    bear thinking about.

    LOL !

    We've had some boards made with red resist in the past. They look a bit wacky.

    I could scan one actually.

    But seriously, if anybody needs a few of something, that's no problem.
    I suppose I could publish the inventory list...

    A lot of this stuff has to be bought by the reel, 1000 or more often
    3000 pieces, so we often have a several-lifetimes supply.

    One of my customers, V*****, decided to make their ESD-sensitive
    boards red. Then their QC people decided that all boards are ESD
    sensitive, so all their boards are now red.

    Maybe *they* want some tantalum caps.

    What's 'a matter? Red's a good color, unless it's a state,
    of course, then blue is better. But you knew that. :)

    We have built boards that were many different colors: red, blue, green (many
    shades), yellow, black, clear, white. Silk screen comes in white, yellow and
    black, maybe others. Our PCB suppliers generally have a large selection of
    solder mask colors to choose from. I think orange adds a second step to the
    process so it costs a little more so watch out with that color.
     
  17. On boards that are not too price sensitive I like to include a few LEDs to
    indicate particular working modes, data activity etc. Looks pretty and quite
    useful in the field for 'at a a glance' analysis.

  18. What a splendidly generous chap!
    Go on, John. "Publish and be damned" as they say. No good deed ever
    goes unpunished, IME. I hope you find otherwise!

    You don't mean over a million 4.7uF gumdrops?
     
  20. In another forum a chap was trying to promote the idea of utilizing
    all those spare bits that we all have lying around by putting the
    available part of our inventories on line in some kind of database.
    It's an interesting concept, though I'm not sure it's practical.
