    Need help identifying Tantalum caps and other goods on PCBs

    I got these out of some CRT monitors. I have learned that tantalum caps can be worth good $$ in bulk.
    Can somebody point out what is good and what is junk?





    Love the site and thanks for any input. Scrapping has been excellent to me in 2014 so far. Over $1500 profit so far.

    Hopefully these can give a little insight into the boards. I would take off that transformer and those taller, long pieces if they are aluminum (cant remember what theyre called right now)

    I save fuses off things like that when I see em. They can be good for fixing microwaves, battery chargers etc, and not easy to find in my area
    Also if you pop the plastic off those little buttons there's usually a little gold or silver colored disk in them, possibly something in the adjusting screws too

    It looks like you have mostly aluminum electrolytic and ceramic capacitors.

    Here's a picture of one type of tantalum capacitor:



    Note the + sign. That makes it easy to tell them apart from ceramic capacitors, which sometimes look pretty similar but don't have the + sign (because they're not polarized):


    There's a pretty good guide to identifying all kinds of components here:

    Thanks for that link.

    An man..you avatar is disturbing. I keep seeing the crazy hamster from that movie G-Force.

    Sirscrapalot - Hurley: Don't pay any attention to him. He's a quarter ferret.

    Bucky: I have no ferret in me, Hurley. That has never been proven.

    Hurley: Then why are you marked down?

    Bucky: I'm on sale! Everyone goes on sale eventually.

    Hurley: This should come as a surprise, but he grew up in the psych ward at UCLA.

    Once you folks take a look at Fl's link....this link should be made a sticky. An I'm still on the first few pages!

    Once again, thanks FL for posting that. Sure does help one know what it is their seeing on the boards.

    I need to go make a scribd account so I can download it properly straight to my kindle for reference when I need it.

    +5 internet points to you sir.

    Sirscrapalot - loving the link.

    Which buttons are you referring to? I see the black rectangular ICs/processors on there. I will cut those off for sure.

    Thanks for the link sir

    That site has been incorporated to the Computer Component Identification sticky:http://www.scrapmetalforum.com/elect...ification.html and scroll to the last post.
    People may laugh at me, but that's ok. I laugh all the way to the bank.

    I hope Bear won't mind me answering your question about which buttons. We talked about them some time back and I've been saving them ever since. They are the push button type switches behind the plastic buttons on your TV. They are about 3/8 inch square with a small button in the middle. The four corners have what seems like a small plastic pin holding the cover on. It's easy to get pliers on the cover and pop it off revealing a gold plated convex disc. This is actually the contact for the switch.
