Ferrite Core for Power Inductor, ER
Electromagnetic Components, Ferrite Components, Ferrite Products
As being a key element in various electrical appliances and electronic products, the magnetic core is expected to have reliable performance and high permeability. The magnetic parts manufactured by Spinel have many outstanding advantages as follows:
1. This type of ferrite core is made from high-temperature low-consumption material and high magnetic permeability material, showing a relatively low power loss at high temperature. We can also customize smaller-size products to suit different application fields.
2. Our company has accumulated 40 years' of experience and expertise in the research and manufacture of magnetic materials, allowing us to select 10+ types of raw materials and product more than 900 types of Ferrite Core with different specifications. The reliable quality and diverse types help us to win a high reputation on the market.
Application
An extensive application of the soft ferrite cores is found in drive transformers, high-frequency transformers, power inductors and planar transformers.
