Core advantages of EE transformer
1. PCB pin terminals are directly through-hole soldered onto the board without the need for additional fixing brackets. They can be produced by automated SMT / assembly lines, ensuring high assembly efficiency.
2. Manganese-zinc ferrite cores operate at frequencies ranging from several kHz to several hundred kHz, with typical power ranging from 1 to 6W.
3. The winding design is flexible, allowing for the creation of multiple auxiliary windings. Input and output voltages, as well as turns ratios, can all be customized to meet the requirements of multiple output channels.
4. Primary and secondary can achieve safety isolation. Insulation can be strengthened as required to meet the voltage safety standards for power products.
5. The small magnetic core requires less material, and the frame and winding processes are mature. The cost-effectiveness of mass production is high.

FAQ
Q: What is the specification of the EE13 high-frequency transformer?
A: EE13 is a small ferrite high-frequency transformer. The magnetic core size is 13mm. The conventional structure is a 5+5 pin pin-type.
A: EE13 is a small ferrite high-frequency transformer. The magnetic core size is 13mm. The conventional structure is a 5+5 pin pin-type.
Q: Why does the EE13 have more than 5+5 pins?
A: The standard frame structure consists of 5 pins for the primary winding and 5 pins for the secondary winding. It reserves sufficient pins for the main winding, auxiliary winding, and multiple output channels, providing the strongest compatibility.
Q: What is the normal temperature rise range of the EE13 transformer?
A: Under rated load, the temperature rise should be ≤ 40K. Working beyond the rated power for a long time will cause rapid temperature increase, buzzing, and efficiency decline.
Q: Can the EE13 transformer be produced using an automatic winding machine?
A: It is fully compatible. It can be automatically wound, automatically wrapped with adhesive tape, and automatically finished, with high consistency and low defect rate, making it suitable for mass production.
Q: What are the main advantages of the EE13 transformer?
A: It is extremely small in size, has low cost, is suitable for high-frequency switching power supplies, is easy to install, has stable mass production, and has a low defect rate. It is the most cost-effective model for small power supplies.
