Abstract
The invention discloses a wide-temperature high-quality factor Q value low-power-consumption magnetic core. The magnetic core comprises side legs, a bottom face and middle columns and is characterized in that the number of the side legs is two, the shapes of the inner sides of the two side legs are provided with inner arcs, the two side legs are connected with the two ends of the bottom face respectively, three middle columns are arranged in the central position of the bottom face, the middle columns are cylindrical, and the cylindrical diameter of the middle columns is smaller than the width of the bottom face. The wide-temperature high-quality factor Q value low-power-consumption magnetic core has the advantages of being ultra low in power loss and high in magnetic conductivity.
Description
Technical field
The invention belongs to magnetic core field, particularly a kind of wide temperature high quality factor Q value low-power consumption magnetic core.
Background technology
This product is to use on charger.In prior art, use the charger charging interval of conventional cores long, the fever phenomenon of appearance, the various fail safe hidden danger and the power loss that easily cause because generating heat.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of ultra-low loss, wide temperature high quality factor Q value low-power consumption magnetic core that magnetic permeability is high.
Technical scheme of the present invention is: a kind of wide temperature high quality factor Q value low-power consumption magnetic core, comprise limit leg, bottom surface, center pillar, it is characterized in that: described limit leg is two, two limit inboard leg shapes are equipped with inner arc, two limit legs are connected with two ends, bottom surface respectively, described bottom center position is provided with center pillar 3, and described center pillar is cylindrical, and the cylindrical diameter of described center pillar is less than bottom width.
The invention has the beneficial effects as follows: this wide temperature high quality factor Q value low-power consumption magnetic core, in extremely wide temperature range 25-120 DEG C, keep the ultra-low loss of material, very low loss temperature coefficient and good temperature stability have realized higher magnetic permeability simultaneously.Such one is to have improved range of application, the 2nd, improve permeability.The quality factor Q value of this product has improved 20%, has improved stability, there will not be the phenomenon of blast.Due to the improvement of material, at varying environment and temperature, the power consumption of this product all decreases simultaneously.Use the trendy charger stand-by power consumption that this product is made only to have 30mW, and the power consumption of old money charger is greatly about 200mW, when use, fever phenomenon no longer occurs.
