    What is this part called????

    I just opened up my xenarc and it broke!!!! The little metal coil had gotten stuck to the glue on the speaker and popped off and unraveled when I pulled the back off of it.
    I circled the part, the picture isn't mine, but it's the same part, same number 151 on it. What is it's name and where do I get it? Can i just pop the other one all the way off and replace it with some solder?

    Looks like an inductor coil the numbers on top will give you the value similar to the way in which capacitors are read. Try your local radio Shack.

    If the coil is unwound, winding it up and soldering back on might work, but it will not work like a new one.

    Check your dimensions with this (hope you have some calipers).

    It appears to be a 150 uH SMT inductor.

    Manufacturer's P/N CDR125-151MC (several manufactuers will make this part, this is only one)

    Its just a coil. Solder it and glue it back on and it'll be fine.

    here is a picture of my coil

    Finally got around to taking an actual picture of it. Still the same part number phc?
    radio shack doesn't have it. and digikey is going to cost me at least 7 bucks, so I really have to be sure on this.

    Well, I'm sure the inductance value is correct, but the package size and or SMT footprint may be different. Study the dimensions in the datasheet and take some measurements.

    But like Altimat said, its just a coil, nothing fancier than a wire wrapped around so many turns. Just solder it back in and use some glue to keep it there.
