FAQ：

Q：Can your high-frequency transformers (e.g., SMD series) meet the high-frequency requirements of 5G base stations?
A：Absolutely. Our SMD series high-frequency transformers are specially designed for high-frequency scenarios, with a maximum operating frequency of up to 500kHz. They also support customized coil winding methods and core materials according to the specific parameters of 5G base station power modules (such as power loss and signal stability requirements), ensuring compatibility with the "high-density and low-interference" operation needs of base stations. Currently, they have been mass-applied in 5G base station projects of major domestic communication equipment manufacturers.
