Nanocrystalline tape is a relatively novel soft magnetic material that allows for smaller cores and improved performance, most often in common mode chokes and current transformers. Magnetics offers a range of anneal properties, permeabilities, cases, and finishes, plus the technical expertise to find the best solution for a given application. This session will address commonly asked questions about the product line, provide a comparison to MnZn ferrite cores of similar size, and review the basic manufacturing process, magnetic characteristics, and design advantages of nanocrystalline cores.
