Detailed core Hui more automatic assembly machine plastic bag core characteristics
Automatic assembly machine core encapsulated in the core is to meet the switching power supply efficiency and reduce the size, weight requirements, the need for a high flux density and high-frequency low-loss transformer core. Although there are high-performance soft magnetic amorphous alloy competition, but price-performance considerations, ferrite material is still the best choice; especially in the field of high frequency 100kHz to 1MHz, the new low-loss high-frequency power ferrite materials have their unique advantages. In order to maximize the use of cores, ferrite materials for high power operation under conditions of high temperature operating range (eg 80 ~ 100 ℃. Below by Hui Xiao Bian tell you more about the core Detailed automatic assembly machine plastic bag the core characteristics.
1, a high saturation magnetic flux density or high amplitude permeability. Thus transformer core at a predetermined frequency has allowed a large flux excursion, the result can reduce the number of turns; It is also helpful ferrite high frequency applications, since the cutoff frequency is proportional to the saturation magnetic flux density.
2, the operating frequency range has a low total core losses. Under given temperature conditions, low core loss would allow high power through.
The requirements are also supplied with a high Curie point, high resistivity, good mechanical strength. (about the Magnetic core Assemble machine)
