minor electronic parts- are these worth anything??

Hi! This is my first real post on the forum. I've been scrapping larger electronics for about a year as a hobby (tvs, computers, monitors, anything else) and have figured out most of the easy base metals and gold plated stuff. I've been trying to figure out some of the minor parts that may have value, especially something such as tantalum capacitors but would cut off of boards about anything that has value.

I'm pretty comfortable with the little monolithic ceramic capacitors but the other stuff I'm pretty clueless with so I'm going to post a number of pixs of the things I've cut off (I'll do 5 tonight). I hope you all can see these ok. I'd like to know if these groups are basically made up of same things and do they have any value.

OK, first pix:

These are common on the various boards I've done, are mostly non magnetic, and usually have "103" or "104" on them.

#2 pix. These are mostly round, uncommon, and have "eyes" on them. The eyes usually are two different colors.

#3 pix. These are common (I probably have more of these with strips on them than anything else). They are magnetic.

Pix #4. These are mostly non-magnetic and most have no printing on them. I've cut a few open they don't appear to have metal inside (sort of crumbly stuff). Somewhat common.

Pix #5. These are mostly magnetic (the bigger one isn't) and many have "100 mkt." printed on them along with some other writing. When cut open there appears to be metal foils inside. Somewhat common

Any help in identifying these would be great. I'll post another set in a couple of days.

# 1- Disc caps.
#2 - _____ caps.
#3 - 1/4, 1/2, 1 watt resistors
#4 - _____ caps
#5 - _____caps
No real value I can see;
Types of Capacitors

Thanks Mechanic!!! In the link you sent, I see several others that I was going to post. Anything on that "Types of Capacitors" web page have scrap value??

On that page, yes, tantalum capacitors. However, as noted by Mechanic 688, there does not appear to be any in the photos you've supplied. For more photo examples of Tantalum capacitors search the archives and/or the buyers/sellers section.

The shiny silver is a dime. Please inform about which electronics have those in them...

;)

Yea I'm picking on the OP, I'm all about sharing the love.

You neglected to tell him that they are worth roughly 10 to a dollar.




Sigh... Sorry

LOL

Well just tell ALL of our secrets MS! ;)

Feeling the love boys, thanks. Too bad its not a 1964 and earlier dime. How many of those fit into a dollar:& ?

The pdf "Scrapper Master Parts List" helped me to eliminate a few more. Here are a few more photos:

Pix #6. Gray-black metallic. Magnetic. Common

http://i1001.photobucket.com/albums/...psb3aabc4d.jpg

About half of these are magnetic.

Magnetic. semi-common

I think I'll scrap a tv in the garage. I know what Cu and Al look like ;)

I think the yellow blocks in the middle photo of your last post are Tanti's.
They are worth money.
They are marked on the positive termanil, which is unusual with capacators.
They are also can shaped, positive termanil marked again, and the 'paint drop' shape.
You will find the paint drops in car electronics mostly.

There's black block tantis that look like the yellow ones you have above, marked on the positive pole.
Now heres a clue, look on the board, you will see numbers beside each componant.
If its a capactor, it'll have a 'C' followed by a number.
The C means its a capactor, the number is for which capactor it is.

Now there's also diodes that look like the black block capactor, beside them there's a 'D' for diode, followed by its number.
I don't know all the letter codes except that the black or white blocks with 4 termanils are 'optocouplers' there's a LED in one end and a photoresistor in the other.
Its a way of sending electrical info around the board without letting actual power go from one part of the board to another. It protects some parts from electrical spikes and such.
There's also bridge rectafiers that look the same, different code, they change AC power into DC power.
The optocouplers have a gold wire on the LED, all LEDs have that gold wire too.

The brown blocks, marked on the board with a C and the number, have Silver and Platinum in the ends. Dunno how much though. They are capactors too.

In the middle photo, appears to be mostly Tantalum capacitors. That type is found in decent quanities on finger cards among other places. For sure, the larger ones @ 4 & 6 o'clock and the one @ 12 o'clock lying horizontal over FDR's head. On those I mention, take note of the solid slightly darker bar across one end. That is the way this style is marked to signify the positive end. The black ones eesakiwi mentioned have a very light (white) bar across the positive end. Generally speaking, from what I have seen the black ones are marked as being HP brand. Tantalums will be magnetic at least on one end, possibly both. Another reasonable, I believe, statement that can be made is that Tantalums will generally be found on better electronics and/or higher grade boards. As of this date, I have never found one on a brown board. I will attempt to provide some good close up photos, so check back.

Except for photo 2, the diagnostic area of interest is in the middle.

This photo shows the ones you have and the black ones. Positive ends pointing towards the middle.

Next we have the epoxy coated capacitors, sometimes referred to as a paint drop shape. I think the multi-color ones at right are cool, some are even pretty.
http://i1305.photobucket.com/albums/...ps4a63a129.jpg
Next are the cannister type or silver casing. What's important to note here is the bulbous area on the wire pointing to the center. This is where another piece of wire of another material is adhered to the wire coming out of the main body.
http://i1305.photobucket.com/albums/...ps8674b11d.jpg
The Tantalum capacitors in this last photo, I believe are considered hermetically sealed. Note the ends toward the middle are rounded and are the positive end.

Thanks eesakiwi and flinthills!!

I'm glad I finally found a few that may be worth $, although at my pace of occasional scrapping it may take years to get a pound. I guess its not surprising that I haven't found a lot of Ta caps because I mostly do old tvs and not as many computers (there's a lot more competition around here over picking up computers off of the "free" category on craigslist than old tube tvs). I also live on one edge of my metro area so to justify a gallon or two of gas, I usually try to chain a couple of stops together and those opportunities then cost me chances at some stuff vs. a guy who's just driving a mile or so to pick something up.

So, besides the occasional tantalum and monolithic ceramic capacitors (and not talking about any obvious gold plated stuff) , there nothing else of these small, minor electronics worth money unless someone goes to the trouble of removing them for reuse, right??

We have a buyer buying transistors, they usually are fastened to a heat sink but sometimes stand alone. All but the one on the left.

Cool, I have a number of those! I wonder do they have to be removed precisely or being cut/twisted from the board ok??

flinthills- I have a few of those little black Ta cap as well. Long, long, long ways from a pound though ;)

This link may help..

You'll find the MLCCs on a lot of various boards.

Find a good way to get them off, an toss'm in a bucket if on boards your not selling to a buyer on here. Or check first if it's ok.

I remove some from certain boards, usually ones I plan to save for being refined.

Make sure you have a "OMG IT"S GOLD!™" Bucket.

Thanks Sir CaL, great suggestions. I've taken the MLCCs off with a wood chisel and then picked up with a magnet. I haven't sold any boards yet because I most haven't dealt with higher end stuff in any large numbers but I'm still refining my options. Meet a board buyer yesterday on the forum that is located in the next door town so I'll be paying him to visit to check things out. And yes, I've established a "gold bearing" box for various things. Haven't got too far beyond that yet.

Thank you all for the various "scraps" of info (couldn't help myself there) :lol:

Hi flinthills

Your information is mostly correct the "silver cased" you referred to are the hermedicly sealed style the last pic is of axial epoxy coated. Ther silver case are wet Ta caps and the have a large crimp at the top.

Look at my blog for better pics you an get to it from my buyers thread.

This forum use to be in English, so the refresh bar kept being hit. What language are you talking? Just kidding. Lot to learn about ewaste but before I do, need to purchase a magnifying glass. The only thing that requires more insight than ewaste is women. Time to go back to the comfort zone, machines that cannot think for you. Your insight is greatly appreciated and now a Texas Instruments calculator bought in 1974 is going to meet it's demise. Anything that I should know before I take the torch to it?

might want to check out Ebay, if its working Patriot. Some old calculators sell for big money. Sorry to side track the thread. Go Lions ;)

Some of those calculators from way back have the white ceramic chips in them.

Older TV's have the tanti capacators in them, check the older 'clunk clunk' channel changers on B&W TV's for Gold plating.
I sometimes find one, yes1, tanti paint drop cap on pre 1990 tvs, its near the ossilator (sp?).
I get that part too, cut the cap off and they look pretty, probably usefull for jewelery.
I'm not meaning the 'crystals' the small can with a frequency on the side, they do have silver in them though, dunno how much.

There's two or three in most tvs. The tiny ones you find in cellphones and high end stuff have the cap welded on with gold, and gold contact pads on them.
