Soft Magnetic Ferrites Manufacturers
Manganese-zinc ferrite is a kind of soft magnetic ferrite. It is a spinel-type structure. It is made of iron, manganese, zinc oxides and their salts by ceramic process. It has a high starting permeability. Generally used in the frequency range of 1 kHz to 10 MHz. It is used to make cores for inductors, transformers, filters, magnetic heads and antenna bars. Often referred to as ferrite cores.

Role of Soft Magnetic Ferrites in Electromagnetic Interference (EMI) Suppression
Electromagnetic interference (EMI) can degrade the performance of electronic devices, especially in high-frequency environments. Soft magnetic ferrites, such as manganese-zinc (MnZn) and nickel-zinc (NiZn) ferrites, are effective at suppressing EMI by increasing impedance for high-frequency signals, thereby reducing noise without affecting the desired signal.
Ferrite cores are commonly used in power supplies, transformers, and signal lines to filter out unwanted high-frequency noise. By absorbing and dissipating EMI, ferrites protect circuits, ensuring stable and efficient operation.
AOHENG offers high-quality MnZn and NiZn ferrite cores with superior magnetic permeability, excellent thermal stability, and low core losses. Our products are tailored for high-performance EMI suppression in a variety of industries, providing reliable noise attenuation in demanding applications.
Soft magnetic ferrites are essential in reducing EMI, and AOHENG’s advanced ferrite cores provide a practical, high-performance solution for manufacturers seeking to enhance electronic device efficiency and reliability.
Optimizing Ferrite Cores for Power Electronics: Reducing Eddy Current and Hysteresis Losses
In power electronics, efficiency is critical. Ferrite cores are widely used in transformers, inductors, and filters to minimize energy losses and improve overall performance. However, to maximize their effectiveness, it’s essential to address two common types of losses: eddy current losses and hysteresis losses.
Eddy current losses occur when alternating magnetic fields induce circulating currents within the core material, leading to heat generation and energy waste. Soft magnetic ferrites, with their high electrical resistivity, help reduce these losses by limiting the magnitude of induced currents. Ferrites' ceramic structure further enhances their resistance to eddy currents, making them ideal for high-frequency applications.
Hysteresis losses arise from the repeated magnetization and demagnetization of the core material as it operates within an alternating magnetic field. These losses are dependent on the material's coercivity. By using ferrite materials with low coercivity, such as manganese-zinc (MnZn) or nickel-zinc (NiZn) ferrites, manufacturers can minimize hysteresis losses, ensuring that the core operates more efficiently with less energy dissipated as heat.
At AOHENG, we produce high-quality ferrite cores specifically optimized for power electronics. Our MnZn and NiZn ferrite cores offer excellent magnetic permeability, low coercivity, and high resistivity, making them highly effective at reducing both eddy current and hysteresis losses. AOHENG’s precision-engineered cores ensure minimal energy losses and optimal performance in demanding power applications, such as transformers, inductors, and switching power supplies.
