SOFT FERRITES
Overview
Soft ferrite is an iron-oxide-based soft magnetic material. This material features high electrical resistance and outstanding magnetic characteristics in high-frequency range although saturation flux density is slightly lower than other soft magnetic materials.
Mn-Zn ferrite 
| Classification of Material | Advantages | Material Name |
|---|---|---|
| Low Power Loss |
Outstanding low power loss in high frequency range (≥100kHz) | ML series |
| High Bm and Power |
Outstanding permeability from room temperature to high temperature (120°C). | MB series |
| High Q |
Low relative loss factor and high impedance | MQ series |
| High Permeability |
High permeability | MP series |
| Stable Permeability against Temperature Change |
Stable permeability in wide temperature range (-20 ~ 100°C). | MT series |
Ni-Zn ferrite
| Classification of Material | Advantages | Material Name |
|---|---|---|
| Low Power Loss |
High saturation magnetic flux density and half power loss compared to NB•NH series. Suitable for high voltage transformer or transformer of DC/DC converter | NL series |
| High Bm |
High saturation magnetic flux density. Suitable for power application | NB series |
| Thermal Shock Resistance |
Outstanding thermal shock resistance with the same performance as NB series. | NH series |
| High Permeability |
High permeability in Ni-Zn materials | NP series |
| Stress and Magnetic Field Resistance |
Small performance change against compressive stress, and less influence by magnetic field. Suitable for resin molded components. | ND•NM series |
