Wholesale Dealers of Earthing Transformer - High frequency transformer – Mingda Detail:

Overview:

Transformers are coupled by magnetic flux linkage, or mutual inductance.

(1) In order to reduce loss, high-frequency transformers often use soft magnetic materials with high permeability and low high-frequency loss as cores.

(2) High-frequency transformers are generally used in small-signal applications, with relatively small size and fewer coil turns.

Mainly used in high frequency switching power supply as high frequency switching power transformer, also used in high frequency inverter power supply and high frequency welding machine as high frequency inverter transformer.

Vertical type and horizontal type is both available for your choice.
