Soft Ferrites

Overview

With our original powder mixing techniques, powder process techniques and annealing techniques, Proterial provides soft ferrite products having excellent magnetic properties. These products contribute to downsizing, weight reduction and higher efficiency for passive components of mobile device and various devices such as for industrial equipment, xEV, etc.

Features

Although 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 geometry and used for wide range of applications.

Proterial have various ferrite materials.

・We have both Mn-Zn ferrite and Ni-Zn ferrite
・Various ferrite materials in 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 suppies 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.

Material (MaDC-F^®)	Features	Material characteristics
ML27D	Low core loss at the frequency 300kHz~500kHz	Material characteristics of ML27D
ML95S	Low core loss at the frequency 500kHz~1MHz	Material characteristics of ML95S
ML91S	Low core loss at the frequency 1MHz~3MHz	Material characteristics of ML91S

Notice for Design: Transformer or Inductor using ML91S shall be designed under the condition of magnetic flux density, Bm, less than 50mT.
