FAQ
Q: What are the advantages of iron powder cores compared to ferrite cores?
A: Iron powder cores offer higher saturation flux density (>1.56T) and strong anti-DC bias saturation capability, suitable for high-current, high-power-density applications. Ferrite cores have lower high-frequency loss but lower saturation flux density (approximately 0.3-0.5T). Iron powder cores are more suitable for power chokes and PFC applications.
Q: What are the characteristics of nanocrystalline alloy cores?
A: Nanocrystalline alloy cores offer high saturation flux density (>1.56T) , low core loss, and excellent temperature stability. In high-frequency, high-power applications, they combine the high saturation characteristics of iron powder cores with the low-loss advantages of ferrite cores. They are suitable for high-end applications such as high-speed rail power systems and solar inverters.
Q: What core shapes are available in this series?
A: Multiple shapes are available, including toroidal, E-type, cylinder, and drum. The appropriate core structure can be selected based on the specific application and installation space.
Q: What is the significance of anti-DC bias saturation capability?
A: In PFC chokes and output choke applications, large DC bias current can cause core saturation, leading to a sharp drop in inductance. The excellent anti-DC bias saturation capability of this core ensures stable inductance under high-current conditions, maintaining filtering effectiveness.
