Commercial Bobbin Cores?

[pinchy911]

I am looking for a company that sells ferrite Bobbin cores that are very small in size. I have been looking for a week now, and the closest I have come is Cosmo Corp (http://www.cosmocorp.com/en/) , but they sell only in shipments of 100. This is for a prototype project and I need at max 10-15.

The dimensions are:

length: 0.63 in
OD: 0.18 in
ID: 0.07 in

What's a bobbin core? Do you mean a pot core?

In any case, try Digikey or Allied Ellectronics. If your needs are very specific, you can also try emailing a manufacturer and request to purchase an evaluation sample.
