EP13
INF
The EP13 Flyback Transformer is engineered for compact isolated DC-DC converter systems and high-frequency switching power supplies requiring stable electrical performance and efficient energy transfer. Built with an EP13 ferrite core structure, it offers balanced magnetic efficiency, compact integration capability, and reliable thermal characteristics for modern electronic power designs.
Its optimized winding structure and compact form factor make it suitable for medium-power electronic applications where PCB space utilization and operational stability are critical.
Compared with smaller EP-series transformers, the EP13 provides enhanced power handling capability and improved thermal performance while maintaining compact system integration advantages.
Customized turns ratios, winding configurations, insulation structures, and output designs are available according to customer application requirements.

Q：If I need to trace the production information of a certain batch of products, can you provide relevant records?A：Yes. We have established a full-process product traceability system. Each batch of products is equipped with a unique "production traceability code." Through this code, you can query information such as raw material suppliers, production workshops, test data, and delivery dates. If you need it, you can apply to customer service for a batch traceability report at any time, and the report will be provided within 1 working day, ensuring product quality is traceable and responsibilities are locatable.
