Advantages

1. High Magnetic Permeability

   • (1) The I-type Mn-Zn power ferrite core has a high initial permeability, showing good inductance characteristics at low frequencies. It can effectively convert low-frequency common-mode interference current into magnetic field energy for storage, reducing the impact of interference signals on the circuit.
   • (2) For example, in electronic devices that require high signal transmission stability, its high magnetic permeability can ensure stable signal transmission and prevent signals from being distorted or lost due to external interference.

2. High Saturation Magnetic Induction Strength

   • (1) Under high current conditions, the I-type Mn-Zn power ferrite core is not easy to enter the saturation state, ensuring that the core can maintain stable performance when the circuit load changes greatly and the current fluctuates, continuously and effectively suppressing electromagnetic interference (EMI).
   • (2) For instance, in switch mode power supplies, the current will fluctuate with changes in load. The high saturation magnetic induction strength enables the core to work normally under such fluctuations, suppress EMI and ensure stable power output.

3. Good Temperature Stability

   • (1) It has good stability within a certain temperature range and can maintain its performance in different working environments. This is very important for electronic devices that need to work under various complex environmental conditions.
   • (2) For example, in automotive electronics, electronic devices may face harsh environments such as high or low temperatures. Good temperature stability can ensure that the core can still function normally under these conditions.

4. Low Loss

   • (1) It has relatively low loss. When working at high frequencies, it can reduce energy loss and heat generation due to eddy currents, improving the working efficiency and stability of the core.
   • (2) Taking high-frequency transformers as an example, the low-loss characteristic can reduce energy loss when the transformer is in a high-frequency working state, improve the efficiency of electric energy conversion, reduce heat generation of the device and extend its service life.

5. High Mechanical Strength

   • (1) It usually has high mechanical strength and can withstand certain physical stress without being damaged easily.
   • (2) In some portable electronic devices, the device may be subjected to external forces such as vibration and collision. The core with high mechanical strength can ensure that it remains intact and works normally under such circumstances.

Application Fields

1. Power Filter

   • (1) The I-type Mn-Zn power ferrite core is often used in power filters to suppress high-frequency noise and interference on the power line, improving the stability and reliability of the power supply.
   • (2) For example, in computer power supplies, it can filter out high-frequency noise from the power grid, provide a stable power supply for computers and protect internal electronic components from interference damage.

2. Inductor

   • (1) Due to its high magnetic permeability and low-loss characteristics, it is often used as the core material for inductors for energy storage, filtering and impedance matching and other functions.
   • (2) In audio amplifiers, inductors combined with the I-type Mn-Zn power ferrite core can achieve better impedance matching through reasonable design, so that audio signals can be better amplified and transmitted while reducing signal distortion.

3. Transformer

   • (1) It is widely used in some small transformers, such as switch mode power supply transformers and pulse transformers.
   • (2) In the switch mode power supply transformers of mobile phone chargers, the I-type Mn-Zn power ferrite core can achieve efficient voltage conversion to meet the charging needs of mobile phones and has a small size, making it suitable for use in portable devices.

4. EMI Suppression in Electronic Devices

   • (1) It is used as an EMI suppression element in electronic products such as computers, TVs, audio equipment and digital communication equipment to reduce electromagnetic radiation and interference.
   • (2) For example, in TVs, it can suppress the emission of electromagnetic interference from internal circuits and also reduce the impact of external electromagnetic interference on the reception of TV signals, thereby improving the quality of images and sound.
