Transformer is a device that transforms AC voltage, current and impedance. When AC current is passed in the primary coil, AC magnetic flux is generated in the core (or magnetic core), which causes voltage (or current) to be induced in the secondary coil. The high frequency transformer is the operating frequency of more than medium frequency (10kHz) power transformer, mainly used in high frequency switching power supply for high frequency switching power transformer, but also for high frequency inverter power supply and high frequency inverter welding machine for high frequency inverter power transformer. High frequency transformers are the most important component of switching power supplies. The copper foil for high frequency transformers from CIVEN METAL is a copper foil specially produced for high-frequency transformers, which has the advantages of high purity, good ductility, smooth surface, high precision, and bending resistance. It is the ideal material for transformer winding.Copper Foil High-precision RA Copper Foil Adhesive Copper Foil Tape *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
