What Is a Nanocrystalline Core?
A nanocrystalline core is a magnetic component made from a unique iron-based alloy with a nanocrystalline microstructure. This structure imparts superior magnetic properties, including high permeability and low core losses, making them ideal for high-frequency and high-current applications. Compared to traditional ferrite cores, nanocrystalline cores offer enhanced performance in terms of noise suppression, thermal stability, and compactness.
