"Communicate, and Violence Disappears"


This chapter is discussing many aspects of core materials for inductors (ferrite, iron-powder) for HF purposes

Select your area of interest: 

o        Introduction and overview


o        Materials and properties


o        Core materials for inductors and transformers


o        Transmission line transformers, introduction


o        Transmission line transformers, examples


o        Ferrites in EMC applications


o        Baluns


o        Iron powder materials for inductors


o        Measurements to core materials


o        Some practical formulas  



Some manufacturers maintain interesting web-sites on core materials for inductors and applications: Ferroxcube, Micrometals,

and Fair Rite (supplier to Amidon). I'm very interested in your remarks on this subject, you may send to on9cvd@amsat.org
