Product Details

 

Nanocrytalline obtained by rapid quenching the liquid alloy, consisting of Fe, Si, Band small amounts of Cu and Nb.

By applying heat treatment to the alloy at higher than its crystallization temperature, this alloy forms a Nano-Crystalline

(grain size of approximately 10 nanometer order), the first ever in the world.

 Satisfy both high saturation magnetic flux density and high permeability.

high saturation magnetic flux density (more than 1T) comparable to Fe-based amorphous 
metal and high permeability (over 10,000 at 100kHz) comparable to Co-based amorphous metal.

It has the advantage of both Fe based and Co based amorphous.

 Excellent temperature characteristics.

Nanocrystlline core has very high Curie temperature (570˚C) which results in small permeability variation (less than +/-10%) at a temperature range of -40 to +150˚C

 Less affected by mechanical stress and very low audio noise emission.

EMC components demonstrate excellent performance in suppression of line noise and radiation 
noise for electrical and electronic devices. Figure below shows examples of various applications. As you can see, 
COILCORE Nanocrystaline core is suitable for a wide variety of products.

The main areas of application are:

  • EMC filters
  • Switched -mode power supplies (SMPS), Power supplies
  • Solar inverters
  • Uninterruptable power supplies (UPS)
  • Welding equipment
  • Wind generators
  • Frequency converters
  • Inductive cooking
