    I've had the following components for some time. I'm not sure where I got them. Any ideas on what they are?

    Scale is in centimeters.

    First image: 66uH +/-20% inductor? (if blue bands are color code.)
    About 2Ω in either direction.

    Second image: Has only the single white dot.
    < 1Ω in either direction.

    Third image: Inductor? Color code gives 680mH (seems high) or 48uH.
    About 1Ω in each direction.

    Thank you.

    the 2nd and 3rd picture are definitely inductors. The second one has probably only 1 turn.

    The second one is also a single loop inductor, the top will have a blob of resin to stop it falling out. Usualy used in RF circuits.
