Advantages
High Saturation Magnetic Flux Density: ET type MnZn power core has a relatively high saturation magnetic flux density, which can maintain low loss under large magnetic flux changes and is suitable for applications involving substantial magnetic energy conversion.
Low Loss: Under high-frequency and high magnetic flux density operating conditions, it exhibits low power loss, contributing to improved overall energy efficiency.
Good Temperature Stability: It has good temperature stability, making it suitable for electronic devices in various environmental conditions.
Good Chemical Stability: Manufactured using ceramic processes, it has stable chemical properties and does not rust, ensuring durability and reliability.
High Resistivity: Compared with metallic magnetic materials, its resistivity is much higher, which helps suppress eddy currents in the circuit, reduce high-frequency noise, and extend the applicable frequency range.
Application Fields
Switching Power Transformers: Due to its high saturation magnetic flux density, low loss, and good temperature characteristics, it is widely used in switching power transformers to enhance power conversion efficiency and reduce device size.
Inductors: Commonly used to manufacture chokes, filter inductors, and other inductors, which play important roles in electronic equipment.
Other Fields: It is also applied in broadband transformers for electronic circuits, Integrated Services Digital Network (ISDN), Local Area Network (LAN), Wide Area Network (WAN), and other fields. Meanwhile, it is also used in lighting equipment, instrumentation, communication equipment, office automation, military products, OA equipment, electronic instruments, aerospace, and other fields.
