"I can't go out and buy one." Um. At 45 cents (US) a pop, they're about half the price of a candy bar.

Edit your text and the title to correct it to what you've just figured out. Then look carefully at it to see if you can make out a part number -- they're usually printed in white on the black body of the piece. That's the number you want to put into a Google search to get the specs (for maximum current).

You'll be able to buy a replacement at RadioShack or any local electronics hobby shop, or online from places like Jameco, Digikey, etc.
