    I am looking for a ferrite slug. The bill of materials calls it a "F29" ferrite slug, threaded, 6mm in length and 2mm diameter.

    Does anyone know of a supplier where I can get these?

    My search engine turned up several hits. Here is one:

    You might consider contacting a manufacturer and asking for a sample. Or, you might salvage a ferrite core from a piece of equipment that operates in that frequency range. Have you tried to find the whole inductor with tuning slug from a parts supplier?

    Finally, do you know that that specification really needs to be met. It may be just what the developer of the circuit had handy. Can you tell us more about your project?


    Edit: You seem to be working on a DIY FM receiver. Maybe you can find a suitable inductor in a scraped receiver.

    Hi John

    Thanks for the info - I looked at the link to Neosid and I've contacted them.

    Here is a pic of the slug:

    I don't have the circuit diagram handy at the moment, but it's a crystal-locked tracking/beacon FM transmitter. The coils need to be wound around the ferrite slug.
