    Hello All,

    I recently purchased a grab bag of coils and inductors. I was a little dissapointed when they were not labeled to know what their values are.

    My question, how would I go about knowing what their values are. My Multimeter meter does not have Inductance. Is their other ways to accomplish the task?

    Thanks so much in advance for the help.

    The easiest way is to get a device for measuring inductances and measure them one by one.

    You may be able to spot those that are identical and just measure one of each type.

    Are they marked at all? If they have a marking of 101 (for example), it might mean 100uH.

    Beware that many multimeters can only measure really high values of inductance that may exceed the values of the ones you have.

    Maybe you can post an image and we can give you some thoughts on the range of inductance you might expect.

    Hi Steve,

    Thanks for the tip. They are marked as 100k. Other inductors do not have markings other than color codes (like resistors)

    here is an image of the inductors

    100k could mean 10...something, maybe 10uH.

    There are colour codes for inductors. That may be the best way to go...

    edit: those may be 10uH 10%

    so 100k means 10 and no multiplier, correct? As far as the color codes link, great link thanks so much
