1K107 Nanocrystalline Magnetic Power C Core

 

A nanocrystalline magnetic power C-core is a wound magnetic core made from a nanocrystalline alloy, shaped like a "C" for high-frequency applications like power transformers, inverters, and current transformers. Its key advantages over traditional materials include significantly lower core losses, higher permeability, and better thermal stability, which enable more energy-efficient and compact designs. These cores are ideal for applications demanding high performance and efficiency, such as in renewable energy systems, industrial power supplies, and electronic energy meters.

 

nanocrystalline C-core Key characteristics and advantages

 

• Low core loss
• High permeability and saturation flux density
• Wide operating frequency
• High temperature stability
• Reduced size and cost

 

 

What are the structural characteristics of nanocrystalline cores?

 

Nanocrystalline cores consist of nanoscale grains (10-20nm) embedded in an amorphous matrix. Their typical composition includes iron, silicon, and boron, with additional elements like copper and niobium. The grain size is much smaller than that of traditional crystalline materials but larger than amorphous materials. The thickness can be as thin as 15-25 microns.

 

 

What advantages do nanocrystalline cores have over amorphous cores?

 

The initial magnetic permeability of nanocrystalline cores can reach 60,000-150,000, significantly higher than that of amorphous materials. Their coercivity can be as low as 0.5 A/m or less, resulting in extremely low iron loss (below 0.1 W/kg at 50Hz), while amorphous cores typically have a coercivity of 1-3 A/m and an iron loss of about 0.2 W/kg at 50Hz. Nanocrystalline cores are suitable for a wider frequency range (20kHz-1MHz) compared to amorphous cores (10kHz-100kHz). Additionally, nanocrystalline cores have a Curie temperature of approximately 570-600℃ and an operating temperature range of -50℃ to 200℃, offering better temperature stability than amorphous cores.

 

 

What are the main application fields of nanocrystalline cores?

 

Nanocrystalline cores are mainly used in high-frequency switching power supply transformers (above 100kHz), common-mode inductors, high-frequency inverters, precision current sensors, electromagnetic compatibility (EMC) devices, and power electronic equipment for new energy vehicles.
