Features：
The core of PQ type high frequency transformer to the ferrite core used the new switching power supply requirements and design, its shape can meet the switching power transformer in high frequency to reduce the copper loss and iron loss requirements, also can adapt to the switching power supply in the temperature rise to the center of the circular column; the winding is easier than that of line capacity increase, the skeleton of the terminal product installation is very reliable. It has the characteristics of small leakage, low loss, wide working frequency and strong anti-interference performance.
