Snoek )	Ferroxcube formerly Philips, now part of the Yageo Group, meanwhile renamed to Chilisin Group	Ferrite Cores, Bobbins, Hardware, EMI Suppression Cores New Handbook / Catalog HB2013 -- PDF file is 10 MB Offline Selection Guide PSG2013 -- PDF file is 29 MB I found an error in the PSG2013 above. Toroid information for the types between TC6.3 to TN29 is missing for the materials 3E27 to 4C65. After reporting this twice I got NO reaction at all. Finally the download is offline now! Above link is to my own backup copy. The missing information can be replaced with the info on pagenumber 91 from the previous PSG2003 (In the PDF page 92). As one extracted page it can also be found here.

The International Magnetics Association Publications

Soft Ferrites : a User's Guide

'Soft ferrites, a users guide' (MMPA SFG-98) is an old publication from the International Magnetics Association, in PDF format. Details are given of advantages, limitations and applications of soft ferrites in magnetic devices; processing; materials and geometries; and core calculations and test procedures.
A glossary of terms is provided together with appendices of magnetic design formulae and ferrite material constants, conversion tables, and wire tables.

Click on the black picture to load my backup copy of the PDF directly, unfortunately a bit crippled OCR version, but that's all there is.....
The original server link doesn't exist anymore.

Meanwhile a newer 2011 version can be found on their site, but also with new OCR artefacts.

And a backup copy on the PE1ABR server.

LINK to a PDF list with the ferrite manufacturers situation before 1969.
A highres scan in PDF from a very complete manufacturers and material table taken from the (1969) book "Soft Ferrites - Properties and Applications" by E.C. Snelling.
A lot has changed.... Ferroxcube (Philips Netherlands) material can also be found in the following sub companies from those days:
Mullard Ltd. UK, Coprim France, Valvo GmbH Germany, Ferroxcube Corp. USA. a.s.o.!

LINK to a PDF list with the ferrite manufacturers situation in 1988.
This one is taken from the 1988 second edition of "Soft Ferrites - Properties and Applications" by E.C. Snelling.
As a result of a less than ideal initial scan in the USA this one is rather vague.
Scan from a printed copy from a copyshop print from a scan, a.s.o.
Also in this one I've done some edit in nearly unreadable words.

Only recently found : the most wonderfull toroid design program I've ever seen!

My own AL calculation software!!
Interface switchable between
NL and the UK language

The VB6 view of the program window in XP.

Click to enlarge

My own VB6 ferrite calculation program to get the AL value from unknown toroids.
After a resonance test put the data in the program, you directly get the AL and Q results.

It works with both a TOP-R as a TOP-C signal feed. Now version 3 which has an embedded documentation module in a separate window. Click for total XP or WIN7 screenshot.

Results are patched from the calculation window to a line in the document window.

The VB6 calculation program

FERRICALC in a ZIP file together with the postscript overlay in Dutch and English. Rename the version you need to the standard name (RINGBLAD3.PS).

The results are patched as an EPS print-overlay in the original (renamed) example PS print file. This *.PS file should be available in the same folder. It is programmed with line drawing commands in postscript code. There is a Dutch and English version available. Also for the fill-in sheet.

As an empty (English) fill-in sheet in PDF it looks like this, English version (use it during measuring), auto-filled-in with the program it looks like this
Click ZIP icon to get the VB6 runtime and OCX files for FERRICALC if needed.

Or go directly via the LINK to the page with all the ferrite backgound information,
and how to make the measurement test setup and all other details.
