This listing is for a lot of 10 toroidal ferrite cores salvaged from old equipment.

They have been grouped by similar size.  See my other auctions for listings with other dimensions.   (Lot #6)

These ferrite rings have the following range of size measurements:

Inner diameter:    From 12mm to 16mm
Outer diameter:   From 20mm to 28mm
Height:                 From 6mm to 10mm

See photograph for a visual concept of size and shape variation.  The photograph shows the actual items you will receive.

Permeability unknown/undetermined.

Will be packaged padded in such a way that they won't knock together in transit, to avoid chips or breakage.
