Ferrite Core for Power Inductor, RM
Inductor Magnetic Core Solution, Soft Magnetic Powder Cores, Anti-Interference Magnetic Cores
Magnetic materials are widely applied in various types of electric appliances, electronic components. Spinel has a wealth of experience in the manufacture and customization of magnetic materials. We can also do adjustment and improvement to product material, structure and property according to customer's actual demands.
The RM magnetic core is mainly used in drive transformers, high-frequency transformers, power inductors and high-frequency choke coils.
Characteristics
1. The production line is equipped with many high-precision and functional processing machines, thus allowing for stable quality and functions of the final magnetic products.
2. All raw materials are purchased from large-scale steel factories in Japan and China. A long-term collaboration further ensures high quality.
3. In each manufacture process, all products must undergo series of strict tests.
4. The magnetic element has a long service life, freeing users from worrying about product quality and aging problems.
Packaging
Before leaving the factory, all magnetic products must be well packed to avoid any possible breakage or damage. Additionally, the packaging manner can also be decided by customers.
