I have googled the crap every way i can, and cannot figure out what these things are!
Good question.
Now give us some proper photographs, less bitwise resolution (1024 by 768 or less) but properly focused. (you need a camera with a "macro" function.)
In particular, a view of the top with the lettering, and the bottom (of all things) to understand how it is put together.
Looks rather like a capacitor.
Where are they from?
Cripes. Why not take a picture of the top, as suggested with proper focus, and crop into the component? I don't need to see a 3000x2000 pixel image of your table.
I suspect it is an inductor. I'd need a better view of the top. Do you have a meter? Can you measure the resistance, and if it reads as open and your meter has a capacitance range, measure it with that?
? 15 mH coil ?
Try a multimeter, measure the resistance and if its infinite then use the capacitance
setting... If the resistance is low its likely an inductor.
lol sorry, i took the picture with a Celestron Microscope zoomed all the way out, i only have the microscope and my phone camera, but only the front camera works on my phone. heh...
Here are a bunch more pictures i tried to take with the front camera of my phone.
They say things like:
"33 mH", "1 mH" etc on the top of each one.
A friend of mine went to school for electronic engineering, but dropped out, he gave me all the little bags of components for school that he had bought from the school, the bags are not labeled.
What is the writing on them? Photos still out of focus.
"33 mH", "1 mH" etc on the top of each one.
The one on the meter is "1 mH"
Then they are inductors or coils.
I cant find a picture of them anywhere?
I've seen inductors like that. The values: mH means millihenry. So 33mH is 33 millihenry.

There are many different ways to construct an inductor and then mount it, which is why you might have difficulty.
In this case, it probably is exactly the same as the bottom right in this picture
from Wikipedia, wound on an open ferrite bobbin, but instead of being covered in heatshrink, is "potted" into a little plastic cylindrical tub and sealed with epoxy (possibly military grade or similar).
they look a lot like these: http://www.digikey.com/catalog/en/partgroup/tsl-series/41415
I'm starting to think that my friend was not completely honest about where he got all these parts from, digging into the box some more, I've found several communication encoding chips, fiber optic lines, and several chips i cant find the datasheets for that have tiny navy government seals on them. "Department of the navy" "United States Of America" "Microsystems Technology Office (MTO)"
if you check surplus, you will find lots of old mil spec and military parts. nothing unusual.

how large of a pallet do you want ?
