What are amorphous magnetic cores?

Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials. These cores can offer superior design alternative when used as the core material in the following components:

Why does amorphous magnetic metal have high permeability?

Amorphous magnetic metal has high permeability due to no crystalline magnetic anisotropy. Amorphous magnetic cores have superior magnetic characteristics, such as lower core loss, when compared with conventional crystalline magnetic materials.

Which amorphous materials are used in power inductor applications?

Nickel–iron alloy (NiFe) cores are commonly used in power inductor applications as they ofer good coercivity compared to ferrites and have higher flux densities as well. The chart in Figure 2 shows that amorphous materials have a good mixture of coercivity and saturation flux density.

Are amorphous cores better?

The Amorphous core will tend to be less expensive, and have lower losses, smaller physical size, better heat dissipation, and are mechanically rugged. The will have lower power loss and smaller however cost will be slightly higher.

What are amorphous metal C-cores?

Amorphous metal C-cores allow for operation at higher frequencies at the same flux level. Where traditional steel cores need to operate at increasingly lower flux densities as the frequency increases. In order to compensate for running at lower flux densities significantly more material is needed.

What is a microlite 100 amorphous toroidal core?

These cores are ideal candidates for PFC boost inductor applications in power supply ranges from 300 to 6kW (for higher power design see Powerlite). Microlite 100 μ are tape wound amorphous toroidal cores with a small gap, which allows the core to achieve permeabilities less than 245.
