The ETD29 high frequency transformer is a medium-power magnetic component designed for switching mode power supply (SMPS) applications. Featuring a horizontal 7+7 pin configuration, it offers a stable mechanical structure and optimized winding space for efficient power conversion.
With its balanced magnetic design and compact footprint, the ETD29 transformer is widely used in power systems requiring reliable isolation, high efficiency, and consistent performance under continuous operation.
The ETD29 transformer is designed to deliver efficient energy transfer with minimized losses across a wide frequency range. It supports stable operation in switching environments and helps reduce thermal stress on surrounding components.
Compared with smaller core sizes, ETD29 offers improved power handling capability and better heat dissipation, making it suitable for medium-power designs. Typical applications can reach approximately 30W–90W depending on design conditions.
