Amorphous Mag-Amp Core‌

FERRTX offers a high-performance Amorphous Magnetic Materials Core designed specifically for precision Mag-Amp (magnetic amplifier) post-regulation in multi-output switching power supplies. Using advanced Amorphous Core Material, these cores deliver exceptional squareness, low losses, and rapid magnetic response—making them a preferred choice for modern server, telecom, and industrial-grade power systems.

Our optimized Amorphous Magnetic Parts enable tighter voltage control, improved efficiency, and simplified circuit architecture compared with traditional silicon-steel or ferrite-based magnetic components.

Core Characteristics & Advantages

High Squareness Ratio for Accurate Regulation

The unique atomic structure of Amorphous Core Material provides a sharp B-H curve transition, ensuring reliable and repeatable magnetic switching behavior—critical for Mag-Amp precision control.

Low Coercive Force

Naturally low coercivity reduces core excitation power and improves regulation response, contributing to stable output voltages even under dynamic load changes.

Excellent Thermal Performance

Low core loss minimizes heat generation, helping SMPS designers maintain tight thermal budgets in compact housings.

Superior Electrical Safety

All cores comply with UL94V-0 flame-retardant standards, ensuring enhanced reliability and safety for high-density power systems.

Consistent Magnetic Behavior

The uniform structure of Amorphous Magnetic Materials Core guarantees consistent saturation characteristics, boosting regulator accuracy and durability over long-term operation.
