Combining the structural advantages of CD-type designs with amorphous material properties, this inductor delivers exceptionally high power density and minimal energy loss within a compact size. Its superior thermal stability and high-frequency performance significantly reduce heat dissipation and enhance system operating efficiency. Purpose-built for renewable energy and high-efficiency industrial power supplies, it enables lighter and more energy-efficient power solutions.
High Power Density CD-Type Amorphous Inductor for Energy-Efficient Systems
Engineered for high-power-density and energy-efficient systems, this CD-type amorphous inductor seamlessly combines the superior thermal performance of a CD structure with the ultra-low core loss of amorphous alloys. Its compact footprint saves valuable PCB space while maintaining exceptional magnetic performance and thermal stability under high-frequency, high-current operating conditions. With minimal heat generation and superior conversion efficiency, it serves as a critical component to boost overall power system performance.

Key Features
Ultra-Low Dissipation & Peak Efficiency: Amorphous alloy technology minimizes both hysteresis and eddy current dissipation, cutting core losses by roughly 80–90% relative to conventional silicon steel. This drastically tempers thermal dissipation and pushes power conversion efficiency to its limits.
High Saturation Resistance: Boasting a high saturation flux density (Bs ≈ 1.2–1.56T)—roughly 3 to 5 times that of standard ferrites (0.3–0.5T)—it effectively prevents magnetic saturation during sharp surge currents, ensuring uncompromising system dependability.
Revolutionary Footprint Reduction: The synergy of high permeability and high Bs enables the same inductance within just 10% to 12.5% of a traditional inductor's physical size, unlocking unprecedented potential for ultra-compact, high-density layouts.
Silent & Low-Vibration Operation: An extraordinarily low magnetostriction coefficient practically eradicates core-induced noise and hum, satisfying the rigorous silence requirements of EV powertrains, high-end audio, and medical equipment.
Broad-Temperature Reliability: Featuring a high Curie point (exceeding 500°C), the core maintains consistent performance across an extreme span from -55°C to 130°C, ensuring reliable operation in thermal-stress environments.
Tailored Magnetic Path: The split-core CD architecture allows precise tuning of the air gap, empowering custom setup of effective permeability to meet exact circuit criteria and ripple current tolerances.
