III Characteristics of EC2828 High Frequency Transformer

EC2828 high-frequency transformer has the characteristics of easy winding, moderate price, and high reliability. The EC/ER2828 high-frequency transformer is a basic type of ferrite core, which is widely used in switching power supplies and various electronic circuits. The oscillation modes include full bridge, half bridge, single ended, resonant, push-pull circuits, etc. It has excellent material properties and is suitable for typical transformer structures. The cylindrical center column of the EC/ER core makes winding easier and increases the cross-sectional area of the winding, which can increase output power. It is suitable for various switching power supply transformers and blocking coils.

4 Application of EC2828 High Frequency Transformer

EC2828 high-frequency transformer is commonly used in main transformers, LLC resonant inductors, DC-DC converters, switch mode power supply chargers, etc.
