1.The secondary winding of dual or multiple winding, appropriate reduce in capacity. 

2.The capacity of the table are based on the conventional EI-0.5mm of our factory, if the customer would like to  use the special needs of 0.35mm EI sheet size based on the same core and frame, the corresponding increase in capacity about 10%. Such as 35X18 core and backbone, using EI piece of 0.5mm, the maximum capacity of transformer capacity is 5.0VA; If the EI switch 0.35mm chip, the maximum capacity can be increased to 5.5VA. 

3.The windings are pin leading, simple, elegant, practical, easy to use, saving labor costs, suitable for mass production. 

4.Skeleton imported fire-retardant material, in line with the EU RoHS Directive; machines inserted silicon steel sheet, high production efficiency. 

5.Twice dipping, automatic baking, rust proof, beautiful appearance. 

6.The table set out in our factory used only skeleton models, more models skeleton, please call us.
