There are two types of ferrite cores used in the production of high frequency transformers: ferrite cores and alloy cores. The ferrite cores are divided into three types: manganese zinc, nickel zinc and magnesium zinc. Alloy cores are also divided into silicon steel, iron powder cores, iron-silicon aluminum, iron-nickel full multi, molybdenum PoMo alloy, amorphous, microcrystalline alloy. Today by the power transformer manufacturers sincere Xinwang technology to everyone a brief explanation of the cores of the ferrite oxygen Hugh series.
The ferrite materials used in high frequency transformers are all soft magnetic ferrite materials. Due to the high resistivity of soft magnetic ferrite material, high frequency loss is small, easy to mass production, good consistency of the product, low cost, is currently the most used in high frequency transformers a magnetic material. Soft magnetic ferrite materials are mainly divided into Mn-Zn ferrite and Ni-Zn ferrite two categories, Mn-Zn ferrite for working frequency in 0.5 ~ 1MHz in the following high-frequency transformers, Ni-Zn ferrite for working frequency in 1MHz or more in the high-frequency transformers, Mn-Zn and Ni-Zn ferrite materials have many varieties, material characteristics are also different, respectively for various different requirements in high frequency transformers and inductors. The main areas include the following.
2.2 Types of ferrite cores for high frequency transformers
Ferrite cores are made by moulding and sintering, and there are many types, mainly E-shaped, can-shaped, U-shaped and ring-shaped, etc.
These are the basic characteristics and application range of ferrite materials
