Nanocrystalline Toroidal Cores
High-performance nanocrystalline toroidal cores for EV chargers, power supplies, and high-frequency transformers. Superior magnetic properties with 99%+ efficiency up to 100kHz.
Overview
Nanocrystalline toroidal cores represent the latest advancement in soft magnetic materials, offering superior performance compared to traditional ferrite and amorphous cores. These high-frequency transformer cores feature ultra-fine grain structure that delivers exceptional permeability (up to 100,000 μ) and minimal core losses at frequencies up to 100kHz.
Ideal for nanocrystalline common mode choke cores, EMI suppression toroidal cores, and power conversion applications, our cores enable compact designs with 99%+ efficiency in demanding environments from -40°C to +130°C.
