Ferrite Cores

US $200.00



Ferrites are high resistivity materials made by compacting MnZn or NiZn plus iron oxides. They derive their magnetic properties by complex interaction of metallic and nonmetallic elements. They are available as bars, toroids, pot cores etc. They are used in inductors, transformers, etc by power electronics industry.

MnZn (MnxZn1-xFe2O4 ) ferrites have higher saturation induction (upto 0.5 T). Their permeability is high (mui = 500 to 20,000). But their resistivity is low. So Mn Zn ferrites are used upto 1 MHz.

NiZn (NixZn1-xFe2O4) ferrites offer lower saturation (< 0.35T). Their permeability is low (mui = 10 to 2000). But their resistivity is high. So NiZn Ferrites are used in 1 MHz to 0.5 GHz range.

Version 6 stores both B(H) and Core Loss properties of each grade in a single excel file. MagWeb’s Ferrites Folder has 288 excel grade files listing magnetic properties of these materials, produced by 6 manufacturers.  The contain 88 B(H) magnetization data sets and 200 core loss data sets.  For names of all these grades, please  click on SMAG – Materials. 

Data in Version 6 also exploited a novel data smoother. It is not unusual for measured data to be rough. Rough data can slow solution convergence.  To prevent such slowdown, MagWeb locates all rough spots in all raw data and spot-cleans them.  Version 6 also extrapolated all smoothed data to saturation. You can download Saturation Flux Density Js of thousands of Grades from SMAG – Materials link.

By downloading this folder you will have 288 files on magnetic properties of all ferrites produced world wide!

Please review the SMAG  Handbook for more technical information of ferrite powder core materials. 

This website is designed for instant download of Folders (containing magnetic property files) via credit card. If you wish to purchase via quote/purchase order, please email to rao@magweb.us
