Grinding Ferrite | Electronics Forums

2013-4-20 · Trimming out 50 core faces doesn't take that long, and the number is exact because the tape is consistent. You then have to remember to pair an untaped core and a taped core together in the build. Grinding works, but you can call Farnell or the like and get them already gapped too. So you could find and buy 100 pre-gapped cores and have 100 ...

Magnetics - Learn About Ferrite Cores

What is a ferrite core? Ferrite cores are dense, homogeneous ceramic structures made by mixing iron oxide (Fe 2 O 3) with oxides or carbonates of one or more metals such as manganese, zinc, nickel, or magnesium. They are pressed, then fired in a kiln to 1300 o C, and machined as needed to meet various operational requirements.
