Nanocrystalline and Amorphous
| Powder Core from Chopped Nanocrystalline Alloy |
| Nanocrystalline alloy powder is obtained by comminution of Fe-based nanocrystalline ribbon. The core is obtained by powder technology using a proper bonding material. The core is characterized by high saturation magnetization (Bs), relatively high magnetic permeability (μ), high saturation magnetic field strength (Hs), low high frequency loss and remarkable frequency characteristics and temperature stability. |
| The product is applicable to various switch mode power supply working under the high frequency and heavy current conditions. It can be used as filter inductance and energy storage in the PFC technology. Its performance is superior to Fe-Ni and Fe-NiMo magnetic powder core (MPP powder core) |
