Ferrite Testing Reveals Significant Performance Variations
For the purposes of testing, Leader Tech engineers selected one of the Company’s most popular FerriShield 28 Material Ferrites with a true 850 permeability. Competitive ferrite samples that exhibited the exact dimensions (outside diameter, inside diameter and length) as well as published permeability were procured for testing. All ferrites in the sample group were analyzed on the same test wire using an Agilent 4396B RF Network/Spectrum/Impedance Analyzer and an Agilent 16192A test meter. Broadband frequencies ranging from 1 MHz to 400 MHz were generated across the test wire and ferrite impedance in Ohms was recorded. The FerriShield 850 perm material outperformed the other ferrites in the test group from 25MHz all the way through the 400MHz range.
The performance variations among manufacturers that offer 850 permeability wideband ferrites are noteworthy. As engineers struggle to eliminate unwanted radio and electromagnetic interference and minimize space and weight allocations, the selection of a high-performance ferrite becomes increasingly important.
“The results of our recent performance tests are impressive. If a manufacturer is looking for the industry’s highest-performance solid or bisected ferrite, they can feel confident in selecting a FerriShield product from Leader Tech”, states Blake Roberts FerriShield Product Manager. In addition to offering the world’s largest, in-stock selection of ferrite sizes and styles, Leader Tech has made a major commitment to providing unrivaled technical support from its Global EMI Shielding Technology Center in Tampa, Florida as well as the Company’s own network of dedicated Regional Sales Engineers.
