Amorphous C core Amorphous cut cores are made from metallic glass materials without a crystalline structure (as seen in silicon steels, permalloys etc.). The amorphous atomic structure results in much higher resistivity than what is exhibited by crystalline alloys; therefore, amorphous cut cores offer excellent frequency response and efficiency. Key Characteristics ? Composition: Fe?Si?B ? Shapes: Cut Cores ? Flux Density (T): 1.56 Amorphous cut cores are a choice solution for high frequency, low loss applications such as uninterruptible power supplies (UPS), SMPS power factor correction (PFC) chokes, filter inductors, and high frequency power transformers and inductors. When compared to ferrite cores, amorphous cores provide a wider operational temperature range, much higher flux capacity, and significantly higher impedance at high frequencies. Amorphous cut cores are strong in both compression and tension. They resist fracture and corrosion.
