SECTION 3 : MPP, High Flux, Sendust or Kool Mu Toroidal Cores. The PDF files in this Section 3 are scanned in directly from the catalog pages. They are fairly large files and may take a longer time to download. Also, these files may not be as sharp as other PDF files in other sections. If you need a clear printed catalog, please request a copy from CWS ByteMark.
