Amorphous
C-Core
Compact, energy-saving magnetic cores for modern transformers and chokes
About the
Amorphous C-Core
The Amorphous C-Core is engineered for use in medium-frequency transformers, chokes, and inverters where low core loss and high efficiency are critical. Built from ultra-thin amorphous metal strips, the C-shaped construction makes it easy to integrate with standard bobbins and windings — improving manufacturability and design flexibility.
Its excellent magnetic properties — including low coercivity and high initial permeability — make the Amorphous C-Core especially well-suited for switching power supplies, PV systems, and high-efficiency industrial electronics.
Performance Highlights
Amorphous C-Cores offer excellent magnetic efficiency, thermal stability, and design flexibility. Below are key advantages that set them apart from traditional core materials.
Reduced Core Loss
Up to 70% lower core loss than traditional silicon steel, improving energy efficiency in demanding applications.
Wide Operating Range
Performs across -40°C to +130°C, making it suitable for harsh or fluctuating thermal environments.
High Saturation Flux
Saturation flux density of approximately 1.56 Tesla ensures reliable magnetic performance under load.
Stable Processing
Precision cutting and annealing enhance dimensional stability and long-term magnetic consistency.
Exceptional Permeability
Initial permeability exceeds 10,000, enabling effective signal transfer and shielding in compact designs.
Flexible Sizing
Available in standard and fully custom dimensions to meet your specific transformer or choke design.
