In Reply to: The reason that so many people have different opinions... posted by Charles Hansen on August 16, 2003 at 09:47:38:
There are a million different formulations and core sizes for ferrite and almost as many ways to improperly impliment them into a design. Since most RF transformers are ferrite based, i have to work with them on a daily basis. Having said that, i've seen circuits with identical designs using various grades of ferrite in the transformers perform as if they were completely different circuits running on different voltages. Some blends of ferrite are FAR superior in terms of power handling, saturation characteristics, thermal stability, long term electrical characteristics, magnetization, etc...With that in mind Charles and stating up front that i typically respect your products and points of view to a great extent, i have to disagree with the the very broad generalizations that you've made in this post. Like anything else, the key to success of ANY circuit is selecting the right parts to get the job done AND minimizing the stress on any given part to the point of increasing reliability due to the lack of stress. As such, using larger cores of high grade material and operating those cores at point that never approach their point of saturation ( thermal or electrical ) will typically provide one with very good and consistent results on a long term basis. Then again, i'm sure that you know this. Why you haven't applied the same line of reasoning and level of understanding to ferrites that you have in other areas of product development is puzzling to me. Sean
