BACKGROUND:
Honestly, these ferrite pot cores are only going to be of interest to those who are technically capable of sitting down and working out whether a constructed inductor using these would suit their purposes.
I am going through my boxes and boxes of salvaged spare parts and came across these ferrites, the big problem (technically) is that I have absolutely no information regarding the ferrite characteristics i.e I do not know what ferrite type material this is.
I have had a hunt around online for ferrites with this sort of coding and have come up with nothing that makes any sense.
I am pretty sure these have been previously removed from one of the myriad of equipment that passes by my "operating table" (the workshop) and most likely they were used (when the windings existed!) as an EMI Suppression component but I probably retained them to 'one day' create some inductors for loudspeaker systems - never happened though!
So, here is the information that I can provide ... it is up to the new owner to do further 'homework' on these.
UNIDENTIFIED MANUFACTURER - Ferrite Pot Cores With Bobbin
Country of origin is unknown, although I suspect in the EU somewhere (much of the salvaged equipment was of German, Swiss, Dutch or Italian origin.)
Ferrite Pot Core, material type is unknown
Standard 'two halves' core with a central removable nylon bobbin which is of course, empty. Nylon central bolt with securing hardware is included.
SOME DIMENSIONS ...
Ferrite core (each half): 42.25mm OD x 14.85mm height. Inside diameter 36.2mm and the central raised section of the core is 17.5mm diameter with a central hole for the nylon mounting bolt.
White nylon bobbin is 35mm OD 19.75mm height. The area available for your windings is 7.5mm wide x 15mm height
COSMETIC CONDITION:
USED (I think)
Clean
NO damage to the ferrite cores nor the White nylon bobbins
These cores are now packed within bubblewrap and then inside a sealed clear plastic packet, waiting to do work once again (nothing worse than ferrite material just hanging around without a purpose in life!)
