Planar Transformer transformer compared with the traditional three-dimensional, the biggest difference between them is the core and coil windings.

General use of E-type planar transformer, RM type, tank-type or ring core, core material for high frequency power ferrite magnetic materials. High-frequency power ferrite materials are the main characteristics of high frequency, core loss, per unit mass under the load of the current big. RE-type core suitable for high density mounting, and installation of high-density trunking not together in the lead, effective shielding, heat dissipation better than the pot core transformer leakage inductance than the E-type core is small, at under 500 ~ 700kHz frequency lower core loss.
The structure of the planar transformer with PCB manufacturing process technology, with precision thin copper sheet or a number of etching in the insulation on the surface of copper windings in the multilayer spiral coil form. Helix and stacked in a flat lead frame ferrite core, the formation of the transformer magnetic circuit
