    Hi guys,

    I just found this site and so far like what I see. I need help identifying a capacitor. I repair and refurbish telephones for a living, and I've just ran into one that I don't know what it is.

    Here's what the number's printed on it are:

    681
    10
    100E

    Now, the "681" part is smaller, so I went and tried a 10v@100μF and I get no life out of this. Any ideas what kind of cap this is? It's found in the newer Cisco phones

    I've got another one that reads:

    651
    10
    100E

    I'm imagining the first is just a burn number....can anyone please help!?

    Do you have a photo of it?

    What are the approximate dimensions?

    Is it surface mount?

    If not surface mount and electrolytic, I'd guess 10uF/100V

    Yes it is surface mount. Unfortunately I don't have my nice camera here with me today, so I can't get a clear picture. It looks like the standard surface mount caps : all silver, black to mark the neg side. I'll take a look at those links supplied, thanks guys....I'm still hunting.

    681= 680 pf
    651=650pf
    10 would be the percent tolerance
    100e the temperature characteristics
    this is just my guess...........good luck
