Amorphous

Amorphous cores are made from metallic glass materials without a crystalline structure (as seen in silicon steels, permalloys, orthonol, and nanocrystalline cores). The amorphous atomic structure results in much higher resistivity than exhibited by crystalline alloys, and therefore 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, magnetic amplifiers (MagAmps), 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 also withstand high amounts of pressure under tension without fracture or corrosion.

Currently available in cut (C shape) cores. Toroids and split cores available upon request.
