What Is an Amorphous Core for PFC Inductors?
Dongguan JH Amorphous provides iron-based amorphous cores for PFC inductors in power electronics such as inverters, switching power supplies (SMPS), and uninterruptible power supplies (UPS). These amorphous cores feature ultra-low core loss, high initial permeability, and excellent thermal stability, making them perfect for applications requiring high-efficiency power conversion.
Amorphous materials exhibit a non-crystalline structure that offers significantly reduced energy loss compared to traditional crystalline materials, especially at high frequencies. This provides lower temperature rise, smaller component size, and better system performance over a wide range of operating conditions.
With a saturation flux density (Bs) of 1.56 T and a Curie temperature of 410°C, these cores can handle high currents and operate reliably even in high-temperature environments (up to +120°C).
