EE25/13/7
INF
The EE25-13-7 flyback transformer is a compact magnetic component designed for low-power offline power supply applications. Based on a standard EE25 ferrite core structure, it provides efficient energy transfer and reliable electrical isolation in high-frequency switching environments. The compact form factor makes it especially suitable for space-constrained designs such as adapters, control boards, and embedded power modules.
Featuring a standardized bobbin structure with multi-pin configuration (commonly 10 pins), the EE25-13-7 transformer supports flexible multi-winding arrangements for multiple outputs or auxiliary power supply. Optimized winding layout and core gap design help reduce leakage inductance and minimize power loss, contributing to improved efficiency and stable system performance. The insulation structure is designed to meet safety requirements for offline applications.
