PQI3527 High-Frequency Transformer Manufacturer Customized DW6807C
We have ER series, EE series, EFD series, EQ series, PQ series, POT series transformers, they are used
for switching power supply,main power transformer. For any given power rating, the higher the frequency, the smaller the transformer can be.Because the transformer is smaller, less copper wire is needed, thus reducing the losses and helping to make the transformer more efficient. Since the core is typically ferrite, a wide variety of geometries are available so the transformer can be tailor-made for the application. Whether additional shielding or a specific form factor is required, the chances are good that a ferrite core exists to meet the requirement.
