High-Efficiency CD-Type Amorphous Inductor for Advanced Power Systems
Our CD-Type Amorphous Inductors utilize premium amorphous alloy core technology designed for next-generation power electronics that demand maximum energy conversion efficiency and ultimate power density. Featuring a split-core (CD-type) architecture, these inductors offer exceptional magnetic properties that far surpass traditional silicon steel and ferrite cores.
Engineered to handle high transient currents while maintaining ultra-low core losses and near-silent operation, they are the ideal choice for high-power PFC circuits, renewable energy, and automotive-grade applications.

Key Features
Extremely Low Core Loss: Amorphous alloy significantly reduces hysteresis and eddy current losses. This yields minimized heat generation and higher power conversion efficiency—delivering typically 80–90% lower core loss compared to traditional silicon steel.
High Saturation Flux Density: Amorphous material offers a high saturation magnetic flux density (Bs ≈ 1.2-1.56T), which is 3-5 times higher than ferrite cores (0.3-0.5T). Allows the inductor to handle large transient currents without saturation, providing excellent reliability
Superior Miniaturization Capability: Thanks to high permeability and high Bs, the exact same inductance value can be achieved in just 1/8 to 1/10 of the physical volume of traditional inductors, enabling ultra-compact, high-power-density designs.
Low Noise & Low Vibration: Utilizing amorphous alloys with an extremely low magnetostriction coefficient, this design virtually eliminates audible core "squealing" or humming. This is a critical advantage for EV, audio, and medical applications.
Excellent Temperature Stability: High Curie temperature (up to 500°C+) ensures stable performance from -55°C to 130°C. Suitable for high-temperature, high-power environments
Adjustable Air Gap Flexibility: The CD-type split-core design allows for precise air gap adjustments, enabling customizable effective permeability to meet your exact circuit and ripple current requirements.

FAQ
Q1: What are the main advantages of an amorphous core inductor?
A1: Compared to traditional silicon steel, amorphous cores cut energy losses by 80% to 90%, meaning much less heat generation. They also handle higher currents while being only a fraction of the size of standard inductors.
Q2: What is the benefit of the CD-type split-core design?
A2: The CD-type split-core design allows us to easily adjust the air gap. This flexibility means we can precisely customize the electrical performance to match your exact circuit and ripple current needs.
Q3: Will these inductors cause audible buzzing or noise?
A3: No. Our amorphous alloy material eliminates high-frequency core "squealing" or humming. This near-silent operation makes them ideal for noise-sensitive applications like electric vehicles (EVs) and audio systems.
Q4: Can I request customized specifications for my project?
A4: Yes, we provide full custom design services. We can adjust the inductance, current ratings, wire specs, and physical dimensions to ensure the component fits your specific power system requirements.
