High Frequency and Planar Transformers

The needs of switch mode power supply have been increasing. SK Electric have been supporting this trend by designing and manufacturing high frequency transformers and inductors.

The planar transformer brings significant advantages. It increases the power density, it is low profile and cost effective due to automated manufacturing techniques.

At SK Electric, we can manufacture planar transformers with a frequency up to 600 kHz and power up to 38kW.
