Why Nanocrystalline Cores Are Rarely Used in High-Frequency Transformers

In the world of magnetic core materials, nanocrystalline cores are often praised for their high saturation flux density, excellent temperature stability, and low core loss—especially in medium to low-frequency power conversion applications. However, when it comes to high-frequency transformers, particularly those operating above 100 kHz, nanocrystalline materials are rarely the first choice. So, why are nanocrystalline cores seldom used in high-frequency transformers? This article explores the material’s physical limitations, design challenges, and cost-performance considerations in detail.
