I am using an ET54 core with a 0.5 mm gap.
Does anyone know the reluctance of this gap ?
Does anyone know the reluctance of this gap ?
I eventually found this but my maths is wrong somewhere.I could not find any reference material specific to that core size that did not also mention core material and winding method with freq of interest.
I did find a good paper with many formula and design suggestions. Perhaps it could clear up some questions you may have or otherwise be helpful.
