Nanocrystalline Transfomer Core

Using nanocrystalline (saturation flux density 1.2-1.5T), eddy current losses are reduced by over 60% compared to ferrite, supporting high-frequency applications (20kHz–1MHz), suitable for switching power supplies and inverters.


High-Frequency Transformer Nanocrystalline Core















High-Frequency Low-Loss Characteristics
Utilizing nanocrystalline material (saturation magnetic flux density 1.2-1.5 T), eddy current losses are reduced by over 60% compared to ferrite. Supports high-frequency scenarios from 20 kHz to 1 MHz, meeting the demands of switching power supplies and inverters.

High Permeability and Precision
Initial permeability reaches 8×10⁴ Gs/Oe. Combined with optimized core air gap design, current sampling linearity error is controlled within ±0.2%, meeting high-precision applications like smart meters.

Wide Temperature Stability
Operating temperature range spans -40°C to +180°C. Magnetic permeability decay rate remains <10% at high temperatures, outperforming traditional silicon steel and ferrite cores.

Miniaturization and Lightweight Design
The nanocrystalline core reduces volume by 50% and weight by 60%, making it ideal for space-constrained applications like new energy vehicles and portable devices.
