I've begun listing some of my smaller inductors below, but will likely never finish with so many types and over 2700 from 0.01 uhy to 1000 mhy so let me know if you don't see what you need and I'll get back to you with what I have. – I indicate in 'Notes' when an image is of the actual inductor(s), but most simply show the style / type of inductor. – Some of the used inductors have leads nearly as long as a new one, but most were removed from PC boards so have leads about 1/4" to 3/4" long depending on the type and size of inductor. |

NEW This is a complete listing of all of the square inductors like this that I have. Lead Length on most is 1/2" making them best for PCB use, but a few have 1.5" leads that could be used most anywhere without having to solder on extension leads. 10/$2 |

Note 1: Inductance was calculated from impedance at noted frequency using method on this web page. Note 2: Inductance was calculated using a capacitor and parallel resonant circuit at noted frequency. In both cases, 1 & 2, current rating of measured inductor, if any, is simply an educated guess. |

There's numerous trays of coils, coil forms, cans, etc. plus many more with vaious forms of ferrite coils and bare ferrite cores. Listing all these items would take more time then I have plus it's not really worth doing so considering what they are worth, but e-mail if you're interested in a number of a particular type, inductance range or some other parameter to help me select which one's you would prefer and be most useful to you and I'll put together a bag full for $5 or so.

For those who asked or may be interested in how I manage to store and keep track of so many items ........... This storage system also works if you're an auto Parts Geek too. You can organize small replacement auto parts in these types of boxes. Larger Parts Geek auto parts may have to be stored in the garage but the small parts can still be stored easily on shelves. |
