Toroidal Nanocrystalline Alloy Cores For Common Mode Choke (CMC)

Toroidal Nanocrystalline Common Mode Choke cores:

Nanocrystalline cores are widely used in common mode choke applications due to their unique combination of magnetic properties. Nanocrystalline cores feature a very high initial permeability which enables a high attenuation in the low frequency range with only a small number of turns. The resulting low winding capacity positively effects the attenuation behavior in the high frequency range. All in all, common mode chokes with nanocrystalline cores feature a distinctive broad-band behavior with almost temperature independent properties in a wide temperature range – this all in a very small component built.

ShOUCORE choose the nanocrystalline ribbon/strip with suitable composition to produce the tape-wound toroidal cores by automatic core winders, then Common Mode Choke Cores will be annealed in magnetic field to meet customers’ requirements.

Features:

1. High saturate induction—reduce volume of CMC.
2. Excellent impedance frequency characteristic.
3. With a small number of turns—reduce copper losses.
4. Outstanding ability to resist unbalanced current.
5. High working temperature.

Applications:

Nanocrystalline alloys has higher Curie temperature compared with ferrite and can stably work even at 180℃; It has higher permeability and saturated inductance. The weight and volume of the nanocrystalline cores are reduced. Usually, the power loss of copper windings is only 50 – 70% of ferrite. Nanocrystalline cores are widely applied to the following industrial applications.

• Air conditioner
• EMC filters
• Electric vehicles
• Solar inverters
• SMPS for LCD TV
• Adaptor for Notebook
• Wind inverters
