Manganese-zinc ferrite is a soft magnetic ferrite material, no magnetism, mainly composed of manganese oxide, zinc oxide and ferric oxide, in high frequency transformers, inductors, filters and motor drive circuits are more applications, the following is the introduction of its characteristics.
First, let's go through a photo to understand it. The picture below shows a MnZn ferrite magnetic bar with a diameter of 0.6mm.
Mn-Zn ferrite core magnetic properties;.
High permeability, tens to tens of thousands.
High saturation magnetic induction (typically 400~500 mT)
Low coercivity (usually in the range of 10~100 A/m)
Best performance at low frequencies (1 kHz to several hundred kHz)
Manganese-zinc ferrite electrical properties;
High resistivity, typically in the range of 10^3 to 10^4 Ω-cm, much higher compared to metallic materials
Low loss, low loss when operating at low frequency bands.
Thermal Characteristics of Mn-Zn Ferrites
Wide operating temperature range, typically -40°C to +150 (some materials even up to 200°C).
The above is an introduction to the characteristics of manganese zinc ferrite. In electromagnetic compatibility (EMC) applications, manganese zinc ferrite can absorb electromagnetic interference, and its high magnetic permeability and low loss make it an ideal choice for power transformers. Used for energy storage and filtering in inductors.
