ROHS CERTIFIED FREQUENCY HIGH VOLTAGE TRANSFORMER THIN PLANAR TRANSFORMER FOR SWITCHING POWER

A planar transformer is an instrument with high frequency, low shape, low height and high operating frequency. The biggest difference between planar transformers and conventional transformers is the core and coil windings. The planar transformer uses a small-sized E-type, RM-type or ring-type ferrite core, usually made of high-frequency power ferrite material, with low core loss at high frequencies; The circuit board is wound and formed, and the winding or the copper piece is stacked on the flat high-frequency iron core to form a magnetic circuit of the transformer. This design has low DC copper resistance, low leakage inductance and distributed capacitance to meet the design requirements of the resonant circuit. Moreover, due to the good magnetic shielding of the magnetic core, radio frequency interference can be suppressed.
