Types and uses of nanocrystalline cores

2021-10-22

Nanocrystalline magnetic cores have high magnetic permeability, high full magnetic induction, low coercivity, and low loss. Suitable for EMC/EMI filter common mode inductors, high frequency transformers, frequency converters, current transformers and other occasions. In the field of new energy, such as solar inverters, wind power generation and other occasions have also been widely used.


Nanocrystalline magnetic sheets have extremely high magnetic permeability. It is mainly used for mobile phone wireless charging receiving terminal, shielding electromagnetic interference to mobile phones, reducing energy loss and improving charging efficiency. It can also be used in other wireless charging areas, such as car wireless chargers. The thinnest thickness of the nanocrystalline magnetic sheet can reach 0.1mm, and the thickness can also be added to achieve higher functions. Various standards and shapes can be customized according to customer needs.


Nanocrystalline cores for common mode inductors, high permeability, used for EMC common mode inductors, EMI filters.


Nanocrystalline magnetic cores have extremely high magnetic permeability, wide frequency characteristics, and still have high magnetic permeability up to 30MHz high frequency. It is very suitable for EMC filters and common mode inductors to suppress common mode noise. Compared with traditional soft magnetic materials, such as ferrite cores, nanocrystalline cores have obvious advantages, high inductance, good filtering effect, small size, fewer copper turns, and high efficiency and energy saving.


Epoxy-coated nanocrystalline magnetic cores are smaller than boxed magnetic cores, require less copper wire, lower copper loss, reduce costs, save energy and save space. It is suitable for miniature filter common mode inductor, ISDN network transformer, network filter, EMC filter, IGBT/Mosfet drive transformer, high-definition camera signal transmission transformer/filter.


New energy electric vehicle DC bus dedicated nanocrystalline cores, customized EMC oval amorphous nanocrystalline cores, frequency converter EMI cores


The elliptical nanocrystalline core is mainly used for common-mode filter inductors, which facilitates directly passing through the bus. It is mainly used between the inverter and the motor to filter high-frequency noise to protect the inverter and motor bearings. It is widely used in new energy electric vehicle powertrains and charging stations.


Nanocrystalline block core, nanocrystalline block is made of 25 micron thick nanocrystalline ribbon. Nanocrystalline block has the characteristics of low core loss and high magnetic permeability. It is suitable for high-frequency transformers, inductors, sensors, and wind turbines.


Nanocrystalline C-core, amorphous C-core upgraded product, with high full magnetic flux density, low coercivity, low core loss, very low noise, high frequency up to 20KHz, suitable for main transformer, output inductance, step-up PFC Choke. Can replace ferrite cores. Standards can be customized.


Amorphous and nanocrystalline void cores are suitable for high-current output inductors, PFC chokes, differential mode chokes, Hall effect sensor concentrators, and have the first-class benefits of full magnetic flux density and low core loss. Replace high magnetic cores with low cost.
