    What part is this coil from a MacBook A2681 ?

    Hi everyone

    I'm struggling to point out what part is this? It is a coil, but the parameters say: 10OHM - 50% - 1A - 0.05Ohm

    So it is a coil with 0201 dimensions, 1A max current, 0.05ohm resistance but what is 10ohm? For a coil we need specs like 1uH or so.

    IAny ideas? It is from a MacBook A2681

    Thank you

    Ferrite bead that applies a resistance at 100 MHz. Much like an electronic resistor that is passive till the part reaches 100Mhz and then applies the noted resistance. IMHO, useless if 10ohms, should be higher resistance to filter out noise but use what they have in place already.

          by mferna14
          Hi, my dear friends., Maybe this might be a stupid question or something I missed or do not know. I have 2 MacBook Air A2681 (Indentical color & EMC #), both LCD screens broken. Before ordering the LCD Screens I confirmed both worked with their respective batteries & AC Adapters, & they did 100%. The LCD Screens came in today & I replaced LCD for the 1st A2681. (Removed Battery Terminal cable for both Laptops before installation of LCDs). Perfect Screen & Booted up fine. But it did not work with battery. I checked the battery connector & it was seated in well/perfectly....

          by Jamey021
          So, what are the odds I shorted the M2 CPU? I got in an a2681 MacBook Air. Liquid damage. Ordered from China and replaced a chip (APL109D 343S00555) cleaned corosion and ultrasonic..The whole 9 yards.
          Last night I put it all together and it came on beautifully. 20V- Apple Logo. I celebrated and knocked the LCD connector loose right away while holding the laptop. Now, it wont boot and it cycles on the volt meter.
          Cycle 20v - .02a then volt meter goes off, then it comes on and rinse and repeat. Classic sign of a MacBook short. I looked at the board with my thermal camera and I can...
