Production Steps

 

1. Nanocrystalline cores for common mode chokes

    - Very high permeability, suitable for EMI common mode chokes.

 

2. Amorphous and nanocrystalline c cores

    - High saturation flux density, and low core loss.

    - Nanocrystalline c cores are the updated material with ultra high performance.

3. Custom cores and magnetic components

    - Oval shape nanocrystalline cores for VFD noise suppresor.

    - Amorphous inductors for output DC choke or PFC choke.

    - Nanocrystalline toroidal cores for common mode choke.
