C Magnetic Core - High Permeability Nanocrystalline

Nanocrystalline C core is an upgrade product of amorphous c core, featuring high saturation flux density, low coercivity, low core loss, and very low noise. It supports higher frequencies up to 20KHz, making it suitable for main power transformers, audio transformers, output inductors, and boost PFC choke coils. It is an excellent replacement for ferrite cores, permalloy cores, and silicon steel cores. Dimensions can be custom-made.

Frequently Asked Questions
What are the main advantages of Nanocrystalline C cores over Ferrite?
Nanocrystalline cores offer higher saturation flux density (1.25T vs ~0.5T for ferrite) and significantly lower core loss at high frequencies, allowing for smaller and more efficient transformer designs.
What is the recommended frequency range for these cores?
While they can operate at various frequencies, they are highly recommended for applications in the 20KHz to 30KHz range.
Are custom dimensions available for the C cores?
Yes, dimensions can be custom-made to meet specific customer requirements and application constraints.
What is the Curie temperature of the material?
The Curie temperature for our Fe-based nanocrystalline material is 560ºC, ensuring stability in high-temperature environments.
Can these cores be used for solar inverters?
Absolutely. They are ideal for solar inverter filters, PFC chokes, and high-efficiency power conversion systems.
What is the stacking factor of the nanocrystalline ribbon?
The stacking factor is greater than 0.75, which contributes to the excellent magnetic performance of the C type cut core.
