Soft ferrite magnetic core material is a material that is easy to magnetize and demagnetize, mainly used to enhance or guide the magnetic flux generated by current. Soft ferrite magnetic core materials are widely used in power electronic circuits, such as voltage and current transformers, saturable reactors, magnetic amplifiers, inductors, chokes, etc. These magnetic devices may need to operate at frequencies from 50/60 Hz down to direct current or above 1 MHz.
Common soft ferrite magnetic core materials include manganese-zinc ferrite corematerialsand nickel-zinc ferrite corematerials. Manganese-zinc ferrite corematerialsare the most common type and have wide applications. Within the manganese-zinc category, a variety of materials can be used, with the selection mainly dependent on the functional requirements of the application. Manganese-zinc ferrites are primarily used for frequencies less than 2 MHz. Nickel-zinc ferrite core materials are characterized by high material resistivity, several orders of magnitude higher than manganese-zinc ferrite corematerials. They are the preferred materials for operating in the range of 1-2 MHz to several hundred MHz. To cover such a wide frequency range and different applications, many nickel-zinc materials have been developed over the years.
Soft ferrite magnetic core materials have broad applications and are commonly used in consumer electronics, household appliances, communications, automotive, LED, and other fields.
Soft ferrite magnetic core materials are used where effective coupling between current and magnetic flux is required. They form an important part of the inductors and transformers used in major communication applications today.
Soft ferrite magnetic core materials for automotive applications can be used under harsh conditions and require inductance with high stability to withstand external stresses during plastic molding processes and changes in operating temperatures.
The main advantages of using LED with soft ferrite magnetic core materials as a light source include energy savings, environmental friendliness, long lifespan, no flickering, and eye protection. If all current lighting sources were replaced by LEDs, the global lighting power consumption would be halved.
With the development of production and application technologies by high-temperature iron powder core manufacturers, soft ferrite magnetic core materials have seen continuous innovation and improvement in fields like inductors, transformers, and filters to meet market demands. Research on soft ferrite magnetic core materials has resulted in the creation of magnetic cores of various shapes made from these materials. Different combinations of these cores have different properties and characteristics to meet varied needs. Cores made from these materials are widely used in broadcasting, television, communications, computer technology, automatic control, aerospace technology, electronic devices, and other IT industries. They are also used in making various types of transformers, inductors, chokes, suppressors, and filters. These factors are driving the development of the soft ferrite magnetic core materials market.
In summary, soft ferrite magnetic core materials cover a wide range of electronic and electrical products and are one of the foundational and pillar industries of the materials sector. With the rapid rise of the electronics and electrical industry, many high-tech soft ferrite magnetic core materials will also be mass-produced and procured. Major market participants in the electrical industry depict an upward trend in the consumption of soft ferrite magnetic core materials. These factors are also bringing more emerging opportunities to the soft ferrite magnetic core materials market.
