PQ, EQ, LP
The central column of the magnetic core is larger than the general magnetic core, the product has less leakage inductance, suitable for small-sized high-power transformers, and the number of output groups cannot be too large;
Features: The ferrite core can meet the requirements of the power transformer for reducing magnetic loss and copper loss. It has a large surface area, good temperature rise characteristics and magnetic shielding characteristics. At the same time, the circular center column is adopted, and the wire package has a large capacity and the winding is easy.
Application: Widely used in switching power supplies, high-power chargers, etc.
