 sendust core ,kool-mu cores ，FeSiAI magnetic powder core
sdndust cores，koolmu cores (sdndust cores) are made with 5. A metal soft magnetic powder core produced from powders made of 4%, 9.6% silicon, and other alloys made of iron. sdndust cores，koolmu cores are widely used. In recent years, due to the rapid growth of nickel media, the excellent cost-effectiveness of sdndust cores，koolmu cores has become prominent. It has become a widely used and widely used soft magnetic core in the current alloy series. Due to the significant increase in demand, which in turn promotes the improvement of production process technology and product quality, it mainly includes solar energy, wind energy conversion, LED drive power supply, voltage regulator, hybrid electric vehicle, UPS continuous power system, high current sensor, switching power supply, input current, line filter, and other aspects. Can replace Magnetics CSC, East, Arnold Foreign sdndust cores，koolmu cores

With the rapid development of electronic technology, the requirements for high-frequency, high-power density, miniaturization, and electromagnetic interference resistance of electronic devices are becoming increasingly prominent, and the market demand is increasing. As a new type of composite electronic material, ,kool-mu Cores has developed rapidly due to its excellent high-frequency magnetic performance, good temperature stability, wide constant magnetic conductivity, low loss, and low cost. It has been widely used in devices such as output inductors, line filters, and power factor correctors.

With the development of electronic technology, the miniaturization and lightness of equipment have led to the necessity of miniaturization of electronic devices. And miniaturization, power density, and the need to make magnetic powder

The high-frequency and low loss characteristics of the core material, while the,kool-mu Cores  has the characteristics of high-frequency and low loss, can be seen from the following formula:

V=3/4 (WR JBF)

V: Volume of magnetic particle core;

W: Power;

R: Resistance;

J: Current density;

B: Magnetic induction intensity;

From the formula, it can be seen that under a certain power, the higher the frequency of ,kool-mu Cores, the smaller the volume. So high-frequency must develop high-frequency electronic materials, and

I,kool-mu Cores has the conditions of high-frequency and low loss.

Now, iron silicon aluminum magnetic powder cores have actually been divided into five categories:

The highest frequency is 8MHz; I=75, with a maximum frequency of 3MHz; I=26, maximum frequency 20MHz, i=60, i=90, maximum frequency 2MHz, i=125, maximum frequency 1MHz. For example,

The loss is i=26, ≤ 54+8% u H, Q value at 300KHz, C0.26 path, V=1V. For FeSiAI magnetic powder core with i=125, the power loss P=140/Kg;

And,kool-mu Cores is P=680W/Kg, which is 3.8 times larger than iron silicon aluminum magnetic powder.

4、 Energy conservation inevitably requires the development of iron silicon aluminum magnetic powder cores

Metal magnetic particle cores mainly include iron nickel molybdenum magnetic particle cores, high flux magnetic particle cores, and ,kool-mu Cores particle cores. These three categories all have superior performance. But iron nickel molybdenum

Magnetic powder contains Ni81%, Mo2%, Fe17%; High magnetic flux magnetic powder core contains 50% Ni and 50% Fe; Iron silicon aluminum magnetic powder cores do not contain precious metal Ni and Mo materials, and in today's shape

Under the formula, Ni and Mo are expensive, and users use,kool-mu Cores to replace them except in the military field.

Iron powder core has excellent performance, low price, and is widely used, but the power loss is too large. Iron silicon aluminum magnetic powder core i=125, yes i=26, 60, 75, 90
The customer can choose your need as follows:                                                                                                             

 

The medium loss is the largest, but compared to iron powder core, the power consumption should be relatively small. The power loss of iron silicon aluminum magnetic powder core is P=140W/KG, and the magnetic loss of iron powder core is P=680W/KG,

The sendust  core is 3.8 times smaller than the iron powder core.

Under the conditions of energy-saving environment,,kool-mu Cores is an inevitable choice.

 

What are the main applications of,kool-mu Cores?
The excellent performance of ,kool-mu Cores was discussed above, and its application will be discussed below.
There are five aspects:

1. High frequency power filter:

Iron silicon aluminum magnetic powder core i=26, power 0-200MHZ, higher than ferrite. Currently, the highest frequency of MnZn is 1MHz, but the current is small, and the frequency of NiZn is relatively low

High, but applied in weak currents. And the ,kool-mu Cores is used in high current applications, which can reach several to a few hundred amperes. Nowadays, switching power supplies are becoming more high-frequency, and filters are becoming increasingly important. High frequency filters have energy-saving effects, such as being widely used in large screen LCD displays.

2. Uninterruptible Power Supply (UPS) Power Corrector (PFC)

The application of uninterruptible power supply is very popular, such as power supply, communication, and electricity, all of which use uninterruptible power supply and are developing towards high-power.

For example, APC in the United States is producing uninterruptible power supplies in its subsidiaries in China, India, and other countries, which are high-frequency high-power uninterruptible power supplies using iron silicon aluminum magnetic powder

The core is C57.2x26.4x15.2 with a permeability of i=26.

France's Meilan Gelan has established a company in Pudong, Shanghai to produce and develop UPS power supplies. They are also moving towards the application of,kool-mu Cores.

3. Power choke

The best choice is to use ,kool-mu Cores for power resonant inductors and phase shift compensation inductors. Power chokes are widely used, with full bridge and half bridge

Bridge chokes, switching power output chokes, PFC inductors, transformers, and other inductors are widely used.

4. Pulse transformers are widely used in communication. When using ferrite, a concentrated air gap needs to be opened, greatly increasing the loss of the air gap. However, when using,kool-mu Cores, no air gap needs to be opened

Gap, without air gap loss, the loss is reduced, which has great advantages.

5. Line output transformer

Line output transformers are now commonly used to use MnZn ferrite, which has a high loss when opening the air gap. However, when using ,kool-mu Cores, there is no need to open the air gap, which reduces the loss and can be used in

High current electrical applications have strong advantages.
