Low - frequency transformers generally use high - permeability silicon steel shee；
High frequency transformers use high frequency ferrite core
4、The number of coil of high frequency transformer and low frequency transformer is different:
The same inductance, high-frequency transformer with the increase of frequency impedance increases slowly, in order to adapt to the high frequency
movement transmission, transformer must be fewer turns to the frequency, even wound as air-core coil
Microwave transmission, some into 3/4 or 1/2 circles.
Our factory only produce the high frequency transformer and got the good reputation in the industrial, EE19 transfomer is very popular is the market.

The entire high frequency transformer is made up of a small number of related cheap components and is easily assembled, so the cost of the transformer is very low.
Because of its small leakage inductance and low switching loss, the stress applied to the connected parts is reduced. Therefore, the parts connected to it can use the parts with lower cost and low power rating.
About the EE19 transformer package
Our company has full-time structural engineers in charge of product packaging. The packaging of overseas products is really important. at present, we mainly use knife card + pearl cotton, blister box + pearl cotton as the packaging method.
And the structure of the plastic disc is also very critical, the transfomers must have a gap to ensure that will not damage!The cartons are made of k-paper; If by sea; Plastic bags inside the cartons (with holes); Add desiccant; It is ok to insert the pearl cotton, pay attention to the full box when packing, the internal can not shake; And the weight should be under 20KG, please see this picture.
EE19 transformer got the below honor certificate.
EE16 High frequency transformers are small components with high surface area to volume ratio and short thermal channels. Good for heat dissipation. The interturn loss between the primary and secondary side windings is small. The special geometry of the core can effectively reduce the core loss. So it can do high flux density. It can work in between 130 ℃ and 40 ℃.
Good coupling between windings and windings can keep the leakage inductance between turns of
windings at the minimum value. The connection from the output end to the auxiliary part is very short and tightly assembled, so the leakage inductance on the connection between the windings is also minimal.
