• Ferrite Core

  Ferrite core is a high-frequency magnetic material mainly composed of metal elements such as iron, manganese, zinc, etc. It has the characteristics of low coercivity and high magnetic permeability.

  
  

• Composition and Preparation

  Ferrite cores are composed of iron oxide and other metal oxides or carbonate compounds, and are made by pressing and high-temperature sintering

  

  Characteristics and Applications

  Ferrite choke have high magnetic permeability, high resistance, and low eddy current losses, making them an ideal material for manufacturing high-frequency circuits such as high-frequency transformers and broadband transformers.

  

• 
  

  In addition, it can also be made into inductors or transformers, which are widely used in instruments, communication equipment, and household appliances.

  How to choose ferrite cores can be approached from the following aspects

  Magnetic properties

  Magnetic permeability: High magnetic permeability means that the coil volume can be smaller under the same inductance requirements.

  Coercivity: Evaluating the ability of ferrite materials to maintain a magnetized state after the removal of a magnetic field.

  Magnetic saturation intensity: measures the magnetic induction intensity of ferrite under strong magnetic field.

  
  

  Physical performance

  Density and hardness: affect the mechanical strength and wear resistance of magnetic cores.

  Thermal expansion coefficient: Evaluating the dimensional stability of magnetic cores under temperature changes.

  
  

  Electrical performance

  Loss tangent: reflects the energy loss of the magnetic core.

  Quality factor: Comprehensive evaluation of the electrical energy conversion efficiency of the magnetic core.

  
  

  Environmental adaptability

  Temperature stability: Ensure that the magnetic core can maintain good magnetic properties in high temperature environments.

  Evaluating the performance of ferrite cores requires comprehensive consideration of multiple aspects such as magnetic properties, physical properties, electrical properties, and environmental adaptability.

  There are many specifications and sizes of ferrite magnetic ring, which can be selected according to the material of magnetic ring, and different coatings can be used to simplify winding and improve breakdown voltage.
  

  
  

  Use of ferrite core
  

  Coils wound around ferrite cores can be made into inductors or transformers, which are widely used in instruments, communication equipment and household appliances. Ferrite cores have many material brands and various geometric shapes, including cylindrical, I-shaped, cap shaped, single hole, double hole, four hole, U-shaped, can shaped, E-shaped, EI shaped, EC shaped, RM shaped, PQ shaped and EP shaped, as shown in the attached figure. The magnetic cores of each shape form a series for users to choose from. Ferrite cores have a wide range of choices. Different materials and shapes can be selected according to different magnetic parameters. Due to their low magnetic loss at high frequency, they are widely used in switching mode power supply (SMPS), radio frequency (RF) transformers and inductors. Ferrite cores of various shapes and sizes are used in inductors, pulse transformers, high-frequency transformers and noise filters in high-frequency power supply and high-quality communication market. Ferrite is characterized by high permeability, good temperature characteristics and low attenuation rate.

  
  

  Specific data of ferrite core

  Compared with the hollow coil of the same volume, the inductor made by winding a coil on the ferrite core has large inductance and high Q value (quality factor). Such as Gu － 22 × 13 can shaped magnetic core. When it is used to make a 4mh inductor, it only needs to wrap 43 turns of coil. If the can shaped magnetic core is not used, it needs to wrap 600 turns to get a 4mh inductor. It can be seen that the volume of inductor or transformer can be greatly reduced after using magnetic core.
