| Frequency Range | 10 kHz - 2 MHz | |
| Resistivity (ρ) | 10^2-10^6 Ω·cm | |
| Curie Temperature (Tc) | 120-250°C | |
| Initial Permeability (μi) | 800-10000 | |
| Saturation Flux Density (Bs) | 300-500 mT |

MnZn ferrites offer higher permeability and saturation flux density, making them suitable for lower frequency applications (up to 1 MHz). NiZn ferrites have higher resistivity and better performance at higher frequencies (above 1 MHz) but lower permeability.
Ferrite cores have much higher electrical resistivity (100-1000 times higher) than laminated steel, which dramatically reduces eddy current losses at high frequencies. They also have lower hysteresis losses and better frequency response characteristics.
Ferrite cores experience decreased permeability and increased core losses as temperature rises. Above the Curie temperature, they lose magnetic properties entirely. Proper thermal management is crucial for maintaining performance in high-power applications.
