Planar Transformer

Planar Transformer is a high-frequency transformer characterized by its low profile, compact height, and 

high operating frequency.Compared to conventional transformers, planar transformers feature a significantly smaller magnetic core, 

with the most notable reduction in height. This compact design is particularly advantageous for power supply equipment 

with strict space constraints, making planar transformers the preferred magnetic component in many applications.

Beyond their structural benefits, planar transformers also offer superior electrical performance, including:

High power density,High efficiency,Low leakage inductance,Excellent heat dissipation,Cost-effectiveness.

Key Features--

--High current density. The wires of a planar transformer are actually planar conductors, so the current density is high.

--High efficiency. The efficiency can reach 98%~99%.

--Low leakage inductance. Approximately 0.2% of the primary inductance.

--Good heat conduction. The hot aisle distance is short and the temperature rise is low.

--Low EMI radiation. Good core shielding can keep radiation to a very low level.

--Small size. The use of a small magnetic core can reduce the size accordingly.

--The parameters have good repeatability. Because the winding structure is fixed and easy to pre-process, the parameters are stable.

--Wide operating frequency range. The frequency can be from 50kHz to 2MHz.

--Wide operating temperature range. The working temperature is -40℃～130℃.

--Good insulation. The planar transformer is composed of overlapping conductive circuits and insulating sheets, thereby ensuring up to 4 kV insulation isolation between windings, primary-secondary and secondary-secondary.
