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