Soft Ferrite Cores

Soft Ferrite Cores

DESCRIPTION

Although the saturation magnetic flux density of soft ferrite materials is lower than other soft magnetic materials, soft ferrite materials have high electric resistance and therefore have outstanding magnetic properties at high frequencies.
Soft ferrite materials can be shaped in various geometries and used for a wide range of applications.

Proterial have various ferrite materials.

  • We have both Mn-Zn ferrite and Ni-Zn ferrite
  • Various ferrite materials in the product line. We provide suitable ferrite material according to applications and required specifications.
Mn-Zn Ferrite

Mn-Zn soft ferrite cores for high frequency power supplies MaDC-F®

MaDC-F® series realized high-performance low core loss ferrite cores in high frequency operation using magnetic domain control technology.

With optimized of main compounds mixing ratio and trace additive elements, and combination of sintering process based on hysteresis analysis, eddy current loss analysis and the original annealing technique, we make Magnetic Domain Control (which derive the name “MaDC®” from), and realize low core loss ferrite materials.

Notice for Design: Transformer or Inductor using ML91S shall be designed under the condition of magnetic flux density, Bm, less than 50mT.
Other Mn-Zn ferrite
Classification of Material Advantages
Low Power Loss Outstanding low power loss in high frequency range (≥100kHz)
High Bm and Power Outstanding saturation magnetic flux density from room temperature to high temperature (120°C)
High Q Low relative loss factor and high impedance
High Permeability High permeability
Stable Permeability against Temperature Change Stable permeability in wide temperature range (-20 ~ 100°C)
For Inductor (Ni-Zn) · For Communication (sensor)(Ni-Zn)
