Detailed Product Description

2-Generation Nanocrystalline cores for High Frequency Power Transformers

2-Generation Nanocrystalline cores for High Frequency Power Transformers

Features:

King Magnetics releases new 2 Generation Nanocrystalline cores for high frequency and high power transformers. With features high saturation flux density, high permeability, much lower core loss, low saturation magnetostriction and good temperature stability. Widely used as main transformer cores for high frequency and high power switched mode power supply.

 

What is different for 2G nanocrystalline core:

 

> Thinner ribbon thickness, low core loss

> Low magnetostriction, low noise

> Higher working frequency, suitable for 20KHz - 50KHz

 

Applications:

> High frequency and high power switched mode power supply

> Laser power supply

> Inverter welding machine

> Electrical plating power supply

> Medium and high frequency heating power supply

> X-ray power supply

> IGBT Inverter

> Uninterruptable power supply (UPS)

 

Characteristics:

> High saturation flux density -- reducing volume of transformer

> High permeability and low coercivity -- improving efficiency and reducing magnetized current and reducing copper loss

> Low core loss -- increasing efficiency and reducing power consumption

> Excellent thermal stability -- continuous working at up to 120℃ 

> Low magnetostriction -- low audible noise compared to other materials

 

Comparison: 1G, 2G nanocrystalline cores vs. ferrite cores
