Nanocrystalline Soft Magnetic Core
Our magnetic cores use a highly controlled annealing method to generate a consistent and very small nanocrystalline microstructure with grain sizes of 10nm. They improve on typical amorphous magnetic characteristics, giving 1/5th the core loss of Fe-based amorphous metal. Nanocrystalline cores have a larger operational temperature range and much greater impedance at high frequencies than ferrite cores.
Their magnetic properties and high saturation magnetic flux density make nanocrystalline cores suitable fore a wide range of applications, including switched-mode power supplies.
Nanocrystalline Cores Applications
- Power transformer
- Frequency converter
- EMC filter
- Pulse transformer
- EV chargers
Thanks to their high permeability, nanocrystalline CMCs can be smaller in size and handle larger currents. CMCs with nanocrystalline cores are also less susceptible to current imbalance and performance loss at high temperatures. This is due to the 1.2 T saturation induction and the wide temperature range.
Low AC losses of the material guarantee for a high efficiency and reliability. Strong casings – available in polyester (130°C) and rynite polyester (155°C) – make them suitable for wrapping with heavy wire.
