Amorphous cut cores are made from metallic glass materials that lack the crystalline structure found in silicon steels, permalloys, orthonol, and nanocrystalline cores. This amorphous atomic structure results in significantly higher electrical resistivity compared to crystalline alloys, delivering excellent frequency response and efficiency.
Amorphous cut cores are an ideal solution for high-frequency, low-loss applications such as uninterruptible power supplies (UPS), switched-mode power supply (SMPS) power factor correction (PFC) chokes, filter inductors, and high-frequency power transformers and inductors. Compared to ferrite cores, amorphous cores offer a wider operational temperature range, higher flux capacity, and significantly greater impedance at high frequencies. They are also mechanically robust in both compression and tension, with strong resistance to fracture and corrosion.
