ETD49 Switching Mode Power Supply High Power Vertical High Frequency Transformer

1.Product Description

The ETD49 magnetic core high-frequency high-power vertical direct insertion transformer is a core component designed specifically for efficient and high-power density switching power supplies. It adopts the classic ETD49 (E-type trapezoidal) ferrite core, which has excellent magnetic circuit efficiency and low leakage inductance characteristics, and is particularly suitable for high-frequency (usually tens of kHz to hundreds of kHz) working environments. The Vertical Straight Plug packaging design facilitates automated PCB board assembly and effectively saves circuit board space. This transformer can handle high power ranging from hundreds of watts to kilowatts, and is widely used in fields such as communication equipment, industrial power supplies, new energy conversion, and high-end server power supplies, achieving a perfect combination of high-efficiency energy transmission and compact size.

These are the five core characteristics of the ETD49 magnetic core high-frequency high-power vertical direct insertion transformer:
1. * * High efficiency and high-power transmission capability * *: Using ETD49 ferrite core, it has a large effective cross-sectional area (Ae) and volume, large magnetic flux capacity, excellent heat dissipation performance, and can stably carry high power ranging from hundreds of watts to kilowatts, meeting the needs of industrial grade high-power power supply.

2. * * Excellent high-frequency characteristics * *: Specially designed for high-frequency switching frequencies (usually tens of kHz to hundreds of kHz), using low loss high-frequency ferrite materials, can significantly reduce magnetic core loss (iron loss), reduce heat generation, and improve the conversion efficiency of the entire power system.

3. * * Low leakage inductance and high magnetic efficiency * *: The circular center pillar structure of the ETD (Economic Transformer Design) magnetic core allows the winding to be wound more tightly and evenly, effectively reducing leakage inductance. This not only improves energy transmission efficiency, but also reduces voltage stress on the switch tube, making the system operation more stable and reliable.

4. * * Vertical Straight Plug saves space * *: The vertical straight plug pin design allows it to be firmly installed upright on the PCB board, greatly saving board space and facilitating high power density and miniaturization design of power products, and is suitable for automated SMT surface mount production.

5. * * Good thermal management and stability * *: The magnetic core has a large size and a large heat dissipation area. When installed vertically, the heat generated by the coil can be directly conducted to the copper foil of the PCB for heat dissipation through the pins. At the same time, there is sufficient air flow space between the magnetic core and the coil, ensuring the thermal stability and long-term reliability of the transformer under high loads.
