Catech is committed to leading supplier of soft magnetic materials and amorphous & nanocrystalline core / ribbon applications.

Nanocrystalline cores for high frequency transformers

by:Catech      2023-04-08


Magnetic core material: Iron-based nanocrystalline magnetic core

Saturation magnetic induction: 1.25T

Magnetic Permeability @ 10KHz:> 20000

Curie temperature (℃): 560

Lamination factor: 0.78

Saturation magnetostriction coefficient (*10^-6):<2

Resistivity (μΩ.cm): 90

Strip thickness: 25μm

Core shape: toroidal, rectangular, C-shaped

High saturation magnetic induction – compared with traditional ferrite cores, it can reduce the size of the transformer

High magnetic permeability – improved efficiency, low excitation power, reduced copper loss

Low coercive force and low iron loss – low transformer temperature rise, energy saving, low carbon and environmental protection

High Curie temperature – good temperature characteristics, working temperature -40 – 130℃

Application field

>> Inverter welding machine

>> Electroplating power supply

>> power amplifier

>> High power laser power supply

>> Communication power supply, railway, high-speed rail power supply

>> High Frequency Induction Heating Power Supply

>> High frequency and high voltage dust removal power supply

>> High-power high-frequency switching power supply

China Amorphous Technology Co., Ltd is the largest manufacturer of nanocrystalline ribbon, which is one of the best product manufactured from us.
have become more diverse in appearance and function thanks to the advanced technology. Choose a that you can trust to deliver an excellent user experience reliable performance at Catech Magnetic Materials.
Although there are various available in the market (such as nanocrystalline transformer, coilcraft common mode choke, and amorphous transformer), recent study results have made this toroidal transformer core price FE based amorphous ribbon a preferred magnetic core manufacturers choice of the people.
China Amorphous Technology Co., Ltd deems nanocrystalline soft magnetic materials as evolutionary rather than revolutionary. We've always had these 'social commerce' marketplaces in some form.
