Custom u cores anyone?
#61 ·
Hi everyone,
I'm new to this forum and I too am looking for core material to use with my experiments. I found something that may be of interest to the forum. I'm fairly sure I've identified the "E" core Stan was either using or planning to using on one of his bi-filler wound coils. Looking at this photo:

The upper most E core in the picture has a part number which reads OP48020???
I looked up Magnetics, Booneville, AR and found this company profile:

Following the link to Magnetics, I then tried several different searches until at last I searched for "4802" without the OP and got this result:

The first part number is for a ferrite E core part number OP48020EC
The permeability is 2,500 and capable of fairly high frequencies. Could this be a clue as to what direction was heading? Has this been noticed before and I just haven't found it in another post already? In any case I'd love to read some thoughts on this.
